γ-Radiolysis of MeOCH₂CH₂OMe gave MeOCH•CH₂OMe, which decomposed to HCOCH₂• and Me₂O. Radiolysis of I (R = H, R¹ = Me; R = R¹ = Me) gave a cyclic radical, which decomposed to RCOCH•R¹ and Me₂CO. Synchronous cleavage of 2 bonds β to the initially formed radical was proposed.

MacLeod, Glesni published the artcileSubstituted 4-methyl-1,3-dioxolanes: solvent interaction products in some commercial beef flavorings, Synthetic Route of 1193-11-9, the publication is Journal of Agricultural and Food Chemistry (1980), 28(2), 441-6, database is CAplus.

Using a modified Likens and Nickerson extraction procedure followed by low-temperature/high-vacuum distillation representative samples of aroma volatiles were obtained from some com. beef flavorings. Prefractionation of concentrates by preparative gas chromatog. facilitated subsequent anal. by combined gas chromatog.-mass spectrometry. One fraction provided a number of similar mass spectra with intense characteristic peaks at m/e 87. These could be 2-substituted-4-methyl-1,3-dioxolanes, but dioxolanes have not been reported as volatile components of meat. Selected 1,3-dioxolanes were synthesized and comparison of their mass spectra and gas-chromatog. retention times confirmed the identities of the unknown components of the simulated meat flavor isolate. Their origin may be explained by interaction of 1,2-propanediol [57-55-6], a commonly used solvent for com. flavors, with carbonyl aroma components, interactions which can modify the flavor characteristics of the product.

The rate constants were determined for the acid hydrolysis of the 10 cyclic acetals obtained by condensation of (CH₂OH)₂ and MeCH(OH)CH₂OH with the following ketones: Me₂CO, MeEtCO, Et₂CO, cyclohexanone, and cyclopentanone. Measurements made by direct dilatometry and calculated with a computer were extremely precise, but the results indicated that the reaction had only limited interest from the point of view of conformational analysis.

Plants are rich in active bio-mols., and these mols. synthesized as secondary metabolites for a wide range of physiol. functions, including defense and food reserve. These plant phytochems. belong to a wide range of categories, including steroids, alkaloids, phenolic compounds, terpenes, saponin, and resin, etc. Watermelon is fruit for the richest source of various bio-active compounds, including vitamins and minerals. Over a period of time numerous hybrid cultivars were designed for com. and large scale cultivation of watermelon. The key question arises among scientific platform for the active phytochems. present in the watermelon hybrid cultivar over wild type. The present study was aimed to carry out a comparative anal. of the presence of various active biomols. in watermelon Citrulus Lanatus hybrid and wild type. We have extracted active phytochems. using multiple solvents, including methanol, acetyl acetate, and chloroform. The methanolic extract was further characterized for active phytochems. using GC-MS for both hybrid and wild type cultivar. Based on phytochem. anal. and preliminary activity anal., i.e., the antimicrobial and antioxidant methanolic extract does possess a comparatively higher biol. activity and hence active biomols. The GC-MS anal. shows a wide range of phytochems., including Alkaloids, Phenolic compounds, Saponin, Quinone, and Coumarin in methanolic extract On the contrary, methanolic extract of wild type cultivar does possess flavonoid, saponnin and steroid, phenolic acids and glyco-conjugates, flavonoids and glyco-conjugates, metabolites of phenylpropanoid pathway, such as gingerol, cinnamic acid, p-coumaric acid, etc.; organic acids such as citric acid, iso-citrate, fumarate, etc.; carotenoid such as beta-carotene metabolism products, curcuminoids; curcubitacin E, monosaccharaides and oligosaccharides, amino acids such as Citrulline, saturated mono and polyunsaturated fatty acids, and compound lipids such as Ceramide and Sphinganine; nucleotide bases such as guanosine, uridine, etc. The study shows watermelon hybrid cultivar are rich in diverse phytochem. over wild type cultivar precisely methanolic extract

Hattori, Gaku published the artcileCopper-catalyzed enantioselective propargylic amination of propargylic esters with amines: copper-allenylidene complexes as key intermediates, Related Products of dioxole, the publication is Journal of the American Chemical Society (2010), 132(30), 10592-10608, database is CAplus and MEDLINE.

Propargyl alcs. and acetates RCH(OX)CCH (R = aryl, heterocyclyl, alkyl, alkenyl; X = H, MeCO), having terminal acetylene moiety, undergo asym. substitution of the hydroxy-function for amine nucleophiles, catalyzed by copper(I) complexes with C₂-sym. chiral diphosphine ligands. The scope and limitations of the copper-catalyzed propargylic amination of various propargylic esters with amines are presented, where optically active diphosphines such as Cl-MeO-BIPHEP and BINAP work as good chiral ligands. A variety of secondary amines are available as nucleophiles for this catalytic reaction to give the corresponding propargylic amines with a high enantioselectivity. The results of some stoichiometric and catalytic reactions indicate that the catalytic amination proceeds via copper-allenylidene complexes formed in situ, where the attack of amines to the electrophilic γ-carbon atom in the allenylidene complex is an important step for the stereoselection. Investigation of the relative rate constants for the reaction of several para-substituted propargylic acetates with N-methylanilines reveals that the formation of the copper-allenylidene complexes is involved in the rate-determining step. The result of the d. functional theory calculation on a model reaction also supports the proposed reaction pathway involving copper-allenylidene complexes as key intermediates. The catalytic procedure presented here provides a versatile and direct method for the preparation of a variety of chiral propargylic amines.
