This review summarizes the transition metal-catalyzed direct C–H functionalization of quinazolinones and quinazolines through C-C, C-N and C-O bond formations. It focuses mainly on the C-H (sp2 or sp3) bond arylation, amination, sulfamidation, acet

A sequence of regio- and stereoselective carbometalation followed by oxidation of ynamides leads to stereodefined fully substituted enolates that subsequently react with various functionalized allyl bromide reagents to provide the enantiomerically pu

The coupling of aldehydes, homoallylic alcohols, and trimethylsilyl azide has been achieved in the presence of phosphomolybdic acid (PMA) in dichloromethane to produce 4-azido- tetrahydropyran derivatives in high yields with all cis selectivity.

Phosphomolybdic acid (H 3 PMo 12 O 40 , a heteropoly acid) is found to catalyze efficiently the Prins cyclization of homoallylic alcohols with aldehydes in water at room temperature to provide tetrahydropyran-4-ol derivatives in high yields with all
