Alkyne [2 + 2 + 2]-Cyclotrimerization Approach for Synthesis of 6,7-Cyclopropylallocolchicinoids.

Atul A More1, Chepuri V Ramana1.   

Abstract

Employing a cobalt-catalyzed [2 + 2 + 2] alkyne cyclotrimerization as the final step, the short and efficient synthesis of cyclopropylallocolchicinoid and its analogues having functional group variations at C9 and/or C10 and C11 of ring C has been accomplished.
