✦ Synopsis

A new variant of palladium-catalyzed stereoselective cyclization has been developed. This process provides an excellent 1,2-diastereocontrol of two new stereogenic centers as well as 1,3asymmetric induction. In addition, desulfonylation of the cyclization product with retention of the initial stereochemistry and conversion of the desulfonylation product to the advanced carbaprostacyclin intermediate is described.
