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.
由N-保护的α-氨基酸在室温下光解其N-羟基吡啶-2-硫酮酯所产生的自由基被叔丁基硫醇有效地淬灭,得到脱羧酸;在适当保护的天冬氨酸和谷氨酸的侧链羧基上已经进行了类似的反应。
