Stereocontrolled formation of cis and trans ring junctions in hydrindane, decalin, and steroid systems by palladium-catalyzed regioselective and stereospecific hydrogenolysis of allylic formates
cis and trans ring junctions can be generated selectively in hydrindane, decalin and steroid systems by the palladium-catalyzed regioselective and stereospecific decarboxylation-hydrogenolysis of allylic formates. The trans junctions were formed from 3β allylic formates of decalin and steroid and 5β allylic formates of hydrindane. The corresponding 3α and 5α formates generate the cis ring junction.
A novel preparative method for homo- and heteroannular conjugated dienes in decalin derivatives by the palladium-catalyzed regioselective elimination reaction of allylic carbonates under mild conditions
Homoannular conjugated dienes in decalin systems can be prepared by the palladium-catalyzed elimination reaction of α-allylic carbonates and heteroannular dienes are obtained from β-allylic carbonates.
Stereocontrolled formation of cis and trans ring junctions in hydrindane and decalin systems by palladium-catalyzed regioselective and stereospecific hydrogenolysis of allylic formates
Both cis and trans ring junctions can be generated selectively in hydrindane, decalin, and steroid systems by the palladium-catalyzed regioselective and stereospecific hydrogenolysis of allylic formates.
