A Fluorous-Tagged 'Safety Catch' Linker for Preparing Heterocycles by Ring-Closing Metathesis

摘要

A fluorous-tagged "safety catch" linker is described for the synthesis of heterocycles with use of ring-closing metathesis. The linker facilitiates the purification of metathesis substrates, the removal of the catalyst, the functionalization of the products, and the release of only metathesis products. The synthesis of a range of heterocycles is described.
