Stereoselective Zirconocene-mediated Ring Transformation of 2-Vinylhetero- cycles to Vinylcarbocycles
摘要:
Stereoselective ring transformation of 2-vinylheterocycles to vinylcarbocycles was efficiently carried out by the use of a zirconocene equivalent ("Cp2Zr"). The transformation proceeded through an intramolecular allylation of Z-allylic zirconocene species to the epoxide or aziridine ring.
