Additions of 1-(aminomethyl)benzotriazoles to enamines, enamides, and vinyl ethers: novel routes to 1,3-diamines and tetrahydroquinolines
摘要:
New methods for the synthesis of 1,3-diamines and of 4-substituted tetrahydroquinolines are described in which the key step is the addition of the condensation products derived from amines, aldehydes, and benzotriazole to enamines, enamides, and vinyl ethers.
