Corey lactone was synthesized in a single pot within 152 minutes in a 50 % overall yield via pot and time economical manner. Latanoprost, an antiglaucoma blockbuster drug, was also synthesized via seven pot reaction with five purifications in a 25 % total yield. One of the key reactions is asymmetric domino Michael/Michael reaction, formal [3+2] cycloaddition reaction, of 3-(dimethylphenylsilyl)propenal and ethyl 4-oxo-2-pentenoate, catalyzed by diphenylprolinol silyl ether, which constructed the core substituted cyclopentanone derivative with nearly optically pure form.
