Generalization of the Benzotriazole-Mediated Introduction of N-Substituents into Amides
摘要:
N-(Benzotriazol-1-ylmethyl) amides 2, easily available by condensation of BtCH(2)OH with amides, are used for the preparation of a variety of N-substituted amides such as the homoallyl, 1,3-butadienyl, and 2,2-diphenylcyclopropyl derivatives by displacement of the benzotriazole group under different conditions.
