PALLADIUM-CATALYZED STEREOCONTROLLED CYCLIZATION OF 1,3-DIENE MONOEPOXIDE: A ROUTE TO A NEW SYNTHETIC INTERMEDIATE FOR DE-AB-CHOLESTANE DERIVATIVE.

The optically active (2R,3R)-3--2-(3-butenyl)-2-methyl-1-cyclopentanone (8) was synthesized as a precursor of vitamin D3 (5) by palladium-catalyzed syn-SN2' cyclization of -
