Effective Synthesis oftert-Butyl-Substituted 3-Carboxy Coumarins in Water Using TEBAC as Catalyst
摘要:
A facile synthesis of novel tert-butyl substituted 3-carboxycoumarin derivatives is described, featuring the one-pot reaction of tert-butyl substituted salicylaldehydes with Meldrum's acid in water using triethylbenzyl ammonium chloride (TEBAC) as catalyst.
