Synthesis of (4S*,5S* )-diphenyl-1,3,4,5-tetrahydro-2H-[1]benzopyrano [4,3-d]pyrimidine-2-thiones by base-catalysed cyclocondensation of (E)-3-benzylideneflavanones with thiourea, and determination of their monoacetylation site

Base-catalysed cyclocondensation of (E)-3-benzylideneflavanones with thiourea has been found to be highly stereoselective, producing (4S*,5S*)-diphenyl-1,3,4,5-tetrahydro-2H-[1]benzopyrano[4,3-d] pyrimidine-2-thiones in high yield, the structure of one of
