Metal-free direct amidation of peptidyl thiol esters with α-amino acid esters

Metal-free direct amidation of peptidyl thiol esters with α-amino acid esters in the presence of bis(trimethylsilyl) acetamide (BSA) has been developed. This general method provides convenient access to N-protected peptides in good yields under mild condi

Dehydrogenation of Indolines to Indoles via Azasulphonium Salts or N-Chloramines

The dehydrogenation of indolines to indoles without using mineral oxidising reagents is described.The conversion was achieved via either azasulphonium salts or N-chloramines, the former route involving milder conditions but a more complex procedure.
