We have demonstrated that chiral 1-(1,3-dithian-2-yl)prop-2-en-1-ols as new scaffolds, obtained by enzyme-catalyzed kinetic resolution, undergo Suzuki-Miyaura cross-couplings and hydroformylation smoothly. Also, we have found that a 1,3-dithianyl group of the products can be removed without any erosion of the enantiopurity under mild conditions.

A convergent synthesis of the prostaglandin F2α analogues, travoprost and bimatoprost, was developed employing Julia-Lythgoe olefination of the structurally advanced phenylsulfone with an enantiomerically pure aldehyde ω-chain synthon. The novel convergent strategy allows the synthesis of a whole series of prostaglandin analogues of high purity from a common and structurally advanced prostaglandin intermediate.
