Guanidine hydrochloride: An efficient catalyst for the synthesis of 2-hydrazolyl-4-thiazolidinone derivatives under solvent free conditions
A Highly efficient protocol has been developed for the synthesis of 2-hydrazolyl-4-thiazolidinone derivatives installing a one pot three component coupling reaction of an aromatic aldehyde, thiosemicarbazide and maleic anhydride using guanidine hydrochloride as highly inexpensive and environmentally friendly catalyst under solvent free condition at 1200C with good to excellent yields, It offers...
متن کاملThiamine hydrochloride (vitamin B1) as an efficient catalyst for the synthesis of 4-(3H)-Quinazolinone derivatives using grinding method.
Herein we explore facile synthesis of 4-(3H)-Qunazolinone derivatives, achieved by the cyclocondensation of anthranilic acid, aromatic amines and triethyl orthoformate in presence of thiamine hydrochloride (Vitamin B1) as a catalyst, using grinding method. This protocol offers several advantages such as reusability of catalyst, excellent yield, shorter reaction time and economic availability.Qu...
متن کاملBF3-SiO2 Nanoparticles: An Efficient Catalyst for the Multi-Component Synthesis of 3-(α-aroylamido) 4-hydroxycoumarin Derivatives in Water
A green and efficient one-pot three component reaction of 4-hydroxycoumarin or 1,3-dimethylbarbutyric acid, aryl glyoxals and amides (thioacetamide) has been developed in the presence of BF3- SiO2 nanoparticles in water. This method has several advantages such as high to excellent product yields in short reaction time, atom economy, environment friendly, reusable catalyst and no need for chroma...
