N-Alkylation of tosylhydrazones in the presence of triphenylphosphine
摘要:
An efficient N-alkylation reaction of tosylhydrazones was developed in the presence of triphenylphosphine; triphenylphosphine played a key role in the transformation. A range of N-alkylated tosylhydrazones were prepared in good to high yields. (C) 2013 Elsevier Ltd. All rights reserved.

Abstract An aluminum chloride promoted Hantzsch reaction of N-tosylhydrazones has been developed. The reaction is general for a wide range of N-tosylhydrazones, and a series of 1,4-dihydropyridines (1,4-DHPs) were prepared in moderate to excellent yields. An aluminum chloride promoted Hantzsch reaction of N-tosylhydrazones has been developed. The reaction is general for a wide range of N-tosylhydrazones
