Polyfunctional imidazoles: VII. 1-aryl-4-chloro-5-[hydroxy(halo)methyl]-1H-imidazoles and their derivatives
摘要:
The reduction of 1-aryl-4-chloro-1H-imidazole-5-carbaldehydes with sodium tetrahydridoborate gave 1-aryl-4-chloro-1H-imidazol-5-ylmethanols which were converted into 5-chloromethyl and 5-fluoromethyl derivatives. 1-Aryl-4-chloro-5-chloromethyl-1H-imidazoles reacted with sodium azide, secondary amines, thiols, and triphenylphosphine to produce the corresponding products of chlorine replacement in the 5-chloromethyl group.
