The first synthesis of β-amino phosphonates using cyclic sulfamidates
摘要:
Cyclic sulfamidates (prepared from a-amino acids and beta-amino alcohols) have been used for the first time for the synthesis of novel beta-amino phosphonates (chiral and achiral) by treatment with dialkyl phosphites using sodium hydride. 2-Substituted and 1,2-disubtituted beta-amino phosphonates have efficiently been prepared following this method. The products are formed in high yield (79-84%) within 8-12 h. (C) 2011 Elsevier Ltd. All rights reserved.

Four stereoisomers of β-methyllanthionine were synthesized by coupling of N-enzyloxycarbonyl-3-methyl-d-cysteine with β-chloroalanine. 1H NMR analysis and retention time in amino acid analysis were studied on these compounds.
