Vinyltriphenylphosphonium Salt-mediated New Synthesis of Functionalized Maleimides
N-Methyl-2-chloroacetoacetamide undergoes a complex reaction with dialkyl acetylenedicarboxylates and triphenylphosphine to produce dialkyl 2-( N-methyl-2-chloroacetoacetamide-2-yl)-3-(triphenylphosphoranylidene)-butanedioates, which undergo elimination-cyclization reactions to produce N-methyl-4-ac...

Zusammenfassung: | N-Methyl-2-chloroacetoacetamide undergoes a complex reaction with dialkyl acetylenedicarboxylates and triphenylphosphine to produce dialkyl 2-( N-methyl-2-chloroacetoacetamide-2-yl)-3-(triphenylphosphoranylidene)-butanedioates, which undergo elimination-cyclization reactions to produce N-methyl-4-acetyl-3-(alkoxycarbonyltriphenylphosphoranylidene)-maleimides. |
