Synthesis of polyacetylenic montiporic acids by means of organosilicon compounds
摘要:
A straightforward synthesis of polyacetylenic montiporic acids A and B has been developed, based upon the selective and sequential substitution of the two trimethylsilyl groups of the readily available 1,4-bis(trimethylsilyl)-1,3-butadiyne. (c) 2005 Elsevier B.V. All rights reserved.

synthetic reaction for the preparation of polyynes; however, chemoselectivity issues have precluded its widespread utilization. Conducting the reaction on a solid-support provides a mechanism to alleviate the chemoselectivity issues and provide products in high purities and yields. Moreover, the polyyne core is a key component to several naturalproducts. Herein, we describe the application of a solid-supported
