摘要

The 4, 17, 30-trithia-[73](1, 3, 5) cyclophane (1) has been prepared by a two-stage, palladium assisted coupling of propargylOTHP with 1, 3, 5-tribromobenzene, followed by sulfide ring closure. The intermediate (8) on deprotection, followed by bromination and reaction with Na2S gives 1 in 58% yield.
