M. Anbazhagan et al., CONVERSION OF CARBONIMIDODITHIOATES TO CARBAMATES, Journal of the Chemical Society. Perkin transactions. I, (11), 1997, pp. 1623-1627
Carbonimidodithioates derived from primary amines or alpha-amino acid
esters have been converted to N-benzyloxycarbonyl derivatives under mi
ld conditions by treatment first with sodium benzyl alcoholate and the
n with water, N-Benzyloxycarbonyl alpha-amino acids have been generate
d from the methyl esters by alkaline hydrolysis or from the allyl este
rs by Pd-0-catalysed de-allylation.
