A series of N-aryl 2-alkenamides were produced efficiently by treating N-aryl 3-(phenylsulfonyl)-propanamides with potassium tert-butoxide in THF at 0 °C. Without isolation, it was further treated with an additional equivalent of potassium tert-butoxide and allyl bromide to give N-allyl N-aryl 2-alkenamides in one pot in good yields. Followed by a ring-closing metathesis reaction, these N-allyl N-aryl 2-alkenamides were respectively converted into corresponding N-aryl a,b-unsaturated g-lactams in moderate yields - 英文摘要: --
