Abstract
The cobalt(I)-catalyzed highly stereoselective [2+2+2] cyclization has been realized for the first time with chiral phosphine oxides substituted linea r enediynes. Depending the substituents on the phosphorus atom, the cycload dition was achieved with a level of diastereoselectivity of 74%. (C) 1999 E lsevier Science Ltd. All rights reserved.
