A novel high-yielding Zn/CuI-mediated coupling of alkyl halides with vinyl sulfones, vinyl sulfonates, and vinyl sulfonamides is described. This protocol is applicable for primary, secondary, and tertiary alkyl iodides and bromides. Alkyl chlorides and aryl and vinyl halides were unreactive under the reaction conditions. Formamide was found to be a superior solvent for obtaining high yields. In the experiment, the researchers used many compounds, for example, 2-Bromomethyl-1,3-dioxolane (cas: 4360-63-8Category: dioxole).

2-Bromomethyl-1,3-dioxolane (cas: 4360-63-8) belongs to dioxole derivatives. Dioxoles, particularly fluorinated dioxoles, are used as co-monomers to make polymers that find use in forming protective coatings for chemical resistance. Dioxole functionalized metal-organic frameworks have also been recently reported.Category: dioxole

Indium-catalyzed annulation of o-acylanilines with alkoxyheteroarenes: synthesis of heteroaryl[b]quinolines and subsequent transformation to cryptolepine derivatives was written by Yonekura, Kyohei;Shinoda, Mika;Yonekura, Yuko;Tsuchimoto, Teruhisa. And the article was included in Molecules in 2018.Synthetic Route of C9H9NO3 This article mentions the following:

An efficient method for the synthesis of heteroaryl[b]quinolines such as I [R = H, 4-OH, 2,3-di-MeO, etc.; R¹ = Me, i-Pr, Ph, etc.; X = N, S] was developed via annulation of o-acylanilines and MeO-heteroarenes using an indium Lewis acid as catalyst for tandem N-C and C-C bond formation. A series of indolo[3,2-b]quinolines was subsequently transformed to structurally unprecedented cryptolepine derivatives Mechanistic studies showed that the N-C bond formation was followed by the C-C bond formation. The indium-catalyzed annulation reaction thus started with the nucleophilic attack of the NH₂ group of o-acylanilines to the MeO-connected carbon atom of the heteroaryl ring in an S_NAr fashion and thereby the N-C bond was formed. The resulting intermediate then cyclized and gave C-C bond through the nucleophilic attack of the heteroaryl-ring-based carbon atom to the carbonyl carbon atom, provided the HA[b]Q after aromatizing dehydration. In the experiment, the researchers used many compounds, for example, 1-(6-Aminobenzo[d][1,3]dioxol-5-yl)ethanone (cas: 28657-75-2Synthetic Route of C9H9NO3).

Under molar ratio of aldehyde/ketone to glycol 1:1.5, mass ratio of catalyst to reactants of 0.5%, and reaction time of 1.0 h, the yield of ketals and acetals was up to 63.2%. The catalyst can be easily recovered and reused. In the experiment, the researchers used many compounds, for example, 2-Ethyl-2-methyl-1,3-dioxolane (cas: 126-39-6Recommanded Product: 126-39-6).

And the article was included in Organic & Biomolecular Chemistry in 2015.Category: dioxole This article mentions the following:

Previously, other groups had reported that Paenibacillus polymyxa NRRL B-30507 produces SRCAM 37, a type IIA bacteriocin with antimicrobial activity against Campylobacter jejuni. Genome sequencing and isolation of antimicrobial compounds from this P. polymyxa strain show that the antimicrobial activity is due to polymyxins and tridecaptin B₁. The complete structural assignment, synthesis, and antimicrobial profile of tridecaptin B₁ is reported, as well as the putative gene cluster responsible for its biosynthesis. This peptide displays strong activity against multidrug resistant Gram-neg. bacteria, a finding that is timely to the current problem of antibiotic resistance.

And the article was included in Journal of Medicinal Chemistry in 1987.Reference of 28657-75-2 This article mentions the following:

The synthesis, cardiac fraction III cyclic nucleotide phosphodiesterase (PDE-III) inhibition, and pos. inotropic activity of a series of 2(1H)-quinazolinones are reported. A general synthesis of the series involves the cyclization of 2-aminoacetophenones with KOCN in AcOH. Modifications at the 4-position of the quinazoline nucleus are best achieved by forming the intermediate N₁-acyl-N₃-phenylurea from the appropriate substituted PhNCO and amide. Polyphosphoric acid effects cyclizaiton to the quinazoline product. Generally the structure-activity relationships for the series parallel the 5-point model previously published for PDE-III inhibition. The most active analog of the series is 5,6-dimethoxy-4-methyl-2(1H)-quinazolinone (I) (ORF 16,600), which has ca. twice the i.v. potency of amrinone and is being developed as an oral cardiotonic.

New generation dopaminergic agents. 6. Structure-activity relationship studies of a series of 4-(aminoethoxy)indole and 4-(aminoethoxy)indolone derivatives based on the newly discovered 3-hydroxyphenoxyethylamine D₂ template was written by Mewshaw, Richard E.;Webb, Michael B.;Marquis, Karen L.;McGaughey, Georgia B.;Shi, Xiaojie;Wasik, Theodore;Scerni, Rosemary;Brennan, Julie A.;Andree, Terrance H.. And the article was included in Journal of Medicinal Chemistry in 1999.Related Products of 3308-94-9 This article mentions the following:

A series of 4-(aminoethoxy)indoles I [R₁ = CH₂Ph, (CH₂)₄Ph, n- Bu, etc.; R₂ = H, Me; NR₁R₂ = isoquinolino; X = H, Cl, Y = H, COCF₃, Cl] and a related series of 4-(aminoethoxy)indolones II [R₁ = Me, CH₂Ph, 2-naphthyl, etc.; R₂ = H, Me, (CH₂)₂, CH₂; X = H, Cl, F] were synthesized and evaluated for their affinity for both the high- and low-affinity agonist states (D₂^High and D₂^Low, resp.) of the dopamine (DA) D₂ receptor. The 4-aminoethoxy derivatives I and II were designed as bioisosteric analogs based on the phenol prototype 3-HOC₆H₄OCH₂CH₂NHCH₂Ph. The indolones II were observed to have high affinity for the D₂^High receptor. Comparison of their previously reported chroman analogs with the more flexible 4-(aminoethoxy)indoles revealed the chroman analogs to be more potent, whereas little loss in D₂^High affinity was observed when comparing the 4-(aminoethoxy)indolones with their resp. chroman analogs. Several regions of the phenoxyethylamine framework were modified and recognized as potential sites to modulate the level of intrinsic activity. A conformational anal. was performed and a putative bioactive conformation was proposed which fulfilled the D₂ agonist pharmacophore criteria based on the McDermed model. Structure-activity relationships gained from these studies have aided in the synthesis of D₂ partial agonists of varying intrinsic activity levels. These agents should be of therapeutic value in treating disorders resulting from hypo- and hyperdopaminergic activity, without the side effects associated with complete D₂ agonism or antagonism. In the experiment, the researchers used many compounds, for example, 2-(3-Chloropropyl)-2-(4-fluorophenyl)-1,3-dioxolane (cas: 3308-94-9Related Products of 3308-94-9).
