Ready protease-catalyzed synthesis of carbohydrate-amino acid conjugates.

The protease-catalyzed synthesis of amino acid est-carbohydrate conjugates as glycopeptide analogues has been achieved in a highly regioselective and carbohydrate-specific manner using amino acid vinyl ester acyl donors and minimally or completely unprotected carbohydrate acyl acceptors, which together probed active sites of proteases to reveal yield efficiencies that are modulated by the carbohydrate C-2 substitutent, and that may be exploited to allow selective one-pot syntheses.

(2-Phenyl-2-trimethylsilyl)ethyl (PTMSE) esters - A novel carboxyl protecting group

A novel silicon-containing protecting group based on the known 2- (trimethylsilyl)ethyl system has been developed for the protection of the carboxylic group, e.g. in peptide chemistry. The new protecting group can be cleaved by treatment with tetra-n-butylammonium fluoride much more rapidly than the known 2-(trimethylsilyl)ethyl group, leading to less side reactions.

SYNTHESIS OF AMINO ACID ESTERS BY PAPAIN

A wide range of N-Boc-amino acid esters were synthesized from N-Boc-amino acids and alcohol using papain as catalyst.Suitable biphasic reaction mixtures were found for most amino acids to achieve high yield of ester synthesis.With N-Boc-L-aspartic and glutamic acids only the α carbonyl group esterified, without racemisation.
