Application of the Solid-Supported Glaser–Hay Reaction to Natural Product Synthesis

The Glaser–Hay coupling of terminal alkynes is a useful 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 natural products. Herein, we describe the application of a solid-supported Glaser–Hay reaction in the preparation of several natural products. These compounds were then screened for antibacterial activity, illustrating the utility of the methodology
