Radicals generated from N-protected α-amino-acids by photolysis of their N-hydroxypyridine-2-thione esters at room temperature are efficiently quenched by t-butyl thiol to give decarboxy-acids; comparable reactions have been carried out on the side chain carboxy groups of suitably protected aspartic and glutamic acids.
