An Aurivillius perovskite nano-structure of SrBi4Ti4O15: efficient catalyst for the preparation of novel dihydronaphtho[2',1':4,5]thieno[2,3-d]pyrimidin-7(6H)-one derivatives using HSBM technique

摘要

An Aurivillius perovskite nano-structure of SrBi4Ti4O15-catalyzed cyclocondensation reaction of 2-amino-4,5-dihydronaphtho[1,2-b]thiophene-3-carboxamide and aldehydes has been carried out by HSBM technique under mild conditions for obtaining 9-aryl-5,8-dihydronaphtho[2',1':4,5]thieno[2,3-d]pyrimidin-7(6H)-ones in good to excellent yields.
