摘要:
We describe an expeditious process that provides ready access to symmetrical and unsymmetrical optically active bispropargylic 1,4-diols. The method employs the use of a recent method we have developed involving terminal acetylenes, Zn(OTf)(2), amine base, and N-methyl ephedrine. The 1,4-diol products should serve as useful building blocks for asymmetric synthesis. (C) 2002 Elsevier Science Ltd. All rights reserved.
