DOI: 10.1021/acs.orglett.8b01865
Abstract: A highly stereoselective, phosphoric acid catalyzed synthesis of cis-3,4-diarylchromanols through reaction of o-hydroxybenzhydryl alcohols and aryl acetaldehydes is reported. The products can be further manipulated to 3,4-dihydrocoumarins, 4 H-chromenes, and chromanes with good overall yields… read more here.
