摘要:
An inverse-electron-demand oxa-Diels-Alder reaction of 5-alkenyl thiazolones with beta,gamma-unsaturated carbonyl compounds enabled by quinine thiourea was studied, which allows the enantioselective synthesis of a broad range of highly functionalized pyranthiazoles bearing three continuous stereocenters. This protocol is adaptable to a wide scope of substrates and has great potential for scale-up synthesis and facile transformation.
