A reasonably stereospecific multistep conversion of Boc-protected alpha-amino acids to Phth-protected beta3-amino acids

A method for the synthesis of beta3-amino acids starting from alpha-amino acids is described. This conversion can be effected by an eight-step procedure which involves the transformation of the carboxylic group into an alkyne followed by a selenium-mediated conversion of the carbon-carbon triple bond to a Se-phenyl selenocarboxylate intermediate. The reactive Se-phenyl selenocarboxylate intermediates can be trapped with water, alcohols or the amine of an amino acid derivative to give beta3-amino acids, beta3-amino esters or mixed peptides, respectively. The whole transformations of the carboxylic group into an alkyne and of the alkyne group into beta3-amino acids may not require purification of the intermediate products but a work-up and isolation procedure of crude materials.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 139009-66-8, help many people in the next few years.Recommanded Product: (S)-N-Boc-2,2-dimethyloxazolidine-4-carboxylic Acid

Poly(l-lysine) modified zein nanofibrous membranes as efficient scaffold for adhesion, proliferation, and differentiation of neural stem cells

Excellent biocompatibility and bioactivity are necessary requirements for a scaffold for nerve repair and regeneration. Natural plant protein zein was chosen as the primary material and poly(l-lysine), which is composed of common amino acids in the human body, was used to modify it. Poly(l-lysine) modified zein (ZPLL) with different PLL contents of 1.46%, 3.57%, and 6.18% was synthesized and nanofibrous membranes were prepared by electrospinning. The hydrophilicity of the membranes improved with an increase of PLL content. The biodegradability of the membranes was proved by in vitro experiments. Compared with pure zein membranes, ZPLL membranes can efficiently improve cell viability, adhesion, proliferation, and differentiation of neural stem cells (NSCs) and the effect of PLL content was further investigated. The results show that when the PLL content was 3.57%, cell adhesion and proliferation proved to be the best and most differentiated toward mature neurons with extensive neurite formation and astrocytes rather than oligodendrocytes. The ZPLL was made into nerve conduits for future study and they may be a promising biomaterial for nerve repair and regeneration.

The enantiomers of 8-<<(4-chlorophenyl)sulfonyl>amino>-4-(3-pyridinylpropyl)octanoic acid (1) and its pyridinyl ether analog (2) were synthesized using the highly diastereoselective method of alkylation of acyloxazolidinone.These enantiomerically pure compounds were compared with the corresponding racemic compounds 1 and 2 for their in vitro activity.Compounds 1, 1R, and 1S and 2, 2S, and 2R were equipotent as thromboxane receptor antagonists (TxRAS) and thromboxane synthase inhibitors (TxSIs) (IC50 = 2-30 nM).Upon oral administration to guinea pigs, the enantiomers inhibited the ex vivo U 46619-induced platelet aggregation with potency similar to that of the corresponding racemic compound.This indicates that the enantiomers have pharmacologic profile and bioavailability similar to that of tha corresponding racemic compound.

Copper(II)-catalyzed amidations of alkynyl bromides as a general synthesis of ynamides and Z-enamides. An intramolecular amidation for the synthesis of macrocydic ynamides

A general and efficient method for the coupling of a wide range of amides with alkynyl bromides is described here. This novel amidation reaction involves a catalytic protocol using copper(II) sulfate-pentahydrate and 1,10-phenanthroline to direct the sp-C-N bond formation, leading to a structurally diverse array of ynamides including macrocyclic ynamides via an intramolecular amidation. Given the surging interest in ynamide chemistry, this atom economical synthesis of ynamides should invoke further attention from the synthetic organic community.
