Synthesis of an ethylene glycol cross-linked amino acid
摘要:
Synthesis of an ethylene glycol-containing amino acid, (2R,9S)-N2-Cbz-N9-Boc-2,9-diamino-4,7-dioxadecanedioic acid 1-phenacyl 10-methyl diester 1, was studied through direct alkylation of N-Boc-L-serine and through BF3-catalyzed ring opening of N-acylaziridinecarboxylates.

A versatile method for the synthesis of chiral 1,4-disubstituted-1,2,3-triazole derivatives starting from easily accessible naturally occurring D-or L-amino acids as chiralsynthons is described. The amino acids were converted into azido alcohols, followed by copper catalyzed [3+2] cycloaddition reactions between the azido alcohols and methyl propiolate and subsequent ester aminolysis with primary
