N-(1-benzotriazol-1-ylalkyl)amides, versatile .alpha.-amidoalkylation reagents. 1. .alpha.-Amidoalkylation of CH acids
摘要:
N-(1-Benzotriazol-1-ylalkyl)amides 2, easily prepared from an amide and an aldehyde with benzotriazole, react smoothly with CH acids under mild conditions to give the alpha-amidoalkylation products in good yields. Benzotriazole aminals also react with CH acids in the presence of methyl iodide.
