Phospha-Michael Addition to In Situ Prepared 5-Arylmethylidene Meldrum’s Acids
摘要:
Knoevenagel condensation reaction of an aldehyde and Meldrum's acid produces a 5-arylmethylidene Meldrum's acid, which undergoes Michael addition of a trialkyl phosphite under solvent-free conditions to afford the title compounds in good yields.
