The prop-2-ynyloxy carbonyl function (POC): A new amino-protecting group removable from sulfur-containing peptides by ultrasonic irradiation with tetrathiomolybdate under mild and neutral conditions
The prop-2-ynyloxy carbonyl function (POC) which can be cleaved undermild and neutral conditions in the presence of benzyltriethylammonium tetrathiomolybdate has been developed as a new protectinggroup for amines.

Propargyl pentafluorophenyl carbonate was synthesised in quantitative yield by the reaction of propargyl chloroformate and pentafluorophenol. All the N-propargyloxycarbonyl (N-Poc) amino acids were obtained in good yield. The use of Poc-OPfp in peptide synthesis has been explored. (C) 2002 Elsevier Science Ltd. All rights reserved.
