摘要：

alpha-Amino acid aminyl radicals have been generated from sulfenamide precursors using Bu3SnH. The aminyl radicals undergo 5-exo-trig cyclisation reactions onto suitably placed N-alkenyl or alpha-alkenyl chains on the amino acids with reasonable diastereoselectivity. The alpha-ester of the amino acid imparts electrophilic behaviour to the aminyl radicals and facilitates cyclisation onto alkenes. (C) 1997 Elsevier Science Ltd.
