High diastereoselectivity in the yang photocyclization via remote hydrogen abstraction reaction

1-Benzoyl-1-(o-alkoxyphenyl)cyclopropanes undergo Yang photocyclization to form dihydrobenzopyranols in a stereospecific manner. The cyclopropyl group at alpha position to carbonyls gives not only a bias in the most stable geometries of the starting ketones but also conformational restriction on geometries of biradical intermediates. More importantly, intramolecular hydrogen bonds seem to give an additional effect on conformational control of the biradical reactivity.

Structure-activity relationship studies of a new series of tripentones (thieno[2,3-b]pyrrolizin-8-ones), led us to prepare several derivatives with antiproliferative activities. The most promising 3-(3-hydroxy-4-methoxyphenyl)thieno[2,3-b]pyrrolizin-8-one 20 (leukemia L1210, IC50 = 15 nM) was shown to be a potent inhibitor of tubulin polymerization.
