The ring-opening polymerization (ROP) of lactones is an effective method for the preparation of biocompatible and biodegradable aliphatic polyesters, for which the development of efficient organocatalysts with high activity and good controllability is highly desirable. A series of novel pyridyl-urea catalysts was synthesized and applied in the solvent-free ROP of lactones and trimethylene carbonate. Combined with 7-methyl-1,5,7-triazabicyclo[4.4.0]dec-5-ene (MTBD), the pyridyl-urea/MTBD systems showed a fast and living/controlled behavior in the ROP, generating polymers with narrow mol. weight distributions. The influences of catalyst structure, type of base, pyridyl-urea/base ratio, feed ratio of monomer/initiator and reaction temperature on the catalytic properties were investigated. A possible mechanism was proposed on the basis of NMR titration and dilution experiments

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Molecules called Efficient synthesis of α-branched purine-based acyclic nucleosides: scopes and limitations of the method, Author is Frydrych, Jan; Slaveetinska, Lenka Postova; Draccinsky, Martin; Janeba, Zlatko, which mentions a compound: 4360-63-8, SMILESS is BrCC1OCCO1, Molecular C4H7BrO2, Related Products of 4360-63-8.

An efficient route to acylated acyclic nucleosides containing a branched hemiaminal ether moiety was reported via three-component alkylation of N-heterocycle (purine nucleobase) with acetal (cyclic or acyclic, variously branched) and anhydride (preferentially acetic anhydride). The procedure employed cheap and easily available acetals, acetic anhydride, and trimethylsilyl trifluoromethanesulfonate (TMSOTf). The multi-component reaction was carried out in acetonitrile at room temperature for 15 min and provides moderate to high yields (up to 88%) of diverse acyclonucleosides branched at the aliphatic side chain. The procedure exhibited a broad substrate scope of N-heterocycles and acetals, and, in the case of purine derivatives, also excellent regioselectivity, giving almost exclusively N-9 isomers.

A novel phospha sugar analog, 2,3-dibromo-3-methyl-1-phenylphosphotane 1-oxide (DBMPP), was prepared from 1-phenyl-3-methyl-2-phospholene1-oxide and evaluated by in vitro MTT method for leukemia cells and microscopic observations for solid tumor cells, e.g., stomach cancer cells. The evaluation revealed clearly that the synthesized phospha sugar analog DBMPP has competent potentials and excellent anti-cancer activities that killed selectively and specifically the leukemia cells of cell lines of K562 and U937 but did not give any damages on healthy leukocyte. Moreover, it was revealed that DBMPP killed solid cancer cells such as stomach cancer cells and melanoma of cell lines of MKN45 and G361. Therefore, DBMPP should exert anti-proliferative effects for different kinds of tumor cells based on the in vitro evaluations. The cell cycle analyses by flow cytometry for K562 and U937 cells clearly demonstrated that the mechanism of the anti-proliferative effect on the human tumor cells is apoptosis induced by DBMPP.

Electrochem. oxidation represents an environmentally friendly solution to conventional methods that require caustic stoichiometric chem. oxidants. However, C-H functionalizations merging transition-metal catalysis and electrochem. techniques are, to date, largely confined to the use of precious metals and divided cells. Herein, the authors report the 1st examples of Cu-catalyzed electrochem. C-H aminations of arenes at room temperature using undivided electrochem. cells, thereby providing a practical solution for the construction of arylamines. The use of Bu4NI as a redox mediator is crucial for this transformation. From mechanistic studies including kinetic profiles, isotope effects, cyclic voltammetric analyses, and radical inhibition experiments, the reaction appears to proceed via a single-electron-transfer (SET) process, and a high valent Cu(III) species is likely involved. These findings provide a new avenue for transition-metal-catalyzed electrochem. C-H functionalization reactions using redox mediators.

Polyoxyethylene-polyamide multiblock copolymers were successfully synthesized from α,ω-poly(oxyethylene)dicarboxylic acid (I), a mixture of two dicarboxylic acids, and an aromatic diisocyanate by 2 synthetic routes, i.e., one-step and two-step methods. In the two-step method, α,ω-diisocyanate-terminated polyamide oligomers, preformed from a mixture of isophthalic acid (II) and azelaic acid (III) with 4,4′-MDI, were reacted with I to form multiblock copolymers. In the one-step method, the reaction components, MDI, II, III, and I, were reacted all together. These polymerizations were carried out in the presence of 3-methyl-1-phenyl-2-phospholene 1-oxide as a catalyst in tetramethylene sulfone, giving multiblock copolymers with inherent viscosities of 0.5-1.1 dL/g. The copolymers were soluble in amide-type solvents, and transparent, ductile, and elastomeric films could be cast from their N,N-dimethylacetamide solutions The tensile strength and modulus of the films thus prepared decreased with an increase in the polyoxyethylene content, whereas the elongation at break increased. The tensile strength, elongation at break, and tensile modulus of the multiblock copolymer films ranged from 47 MPa, 160%, and 1.1 GPa, resp., to 15 MPa, 880%, and 12 MPa, resp.
