RCM-Mediated Synthesis of Trifluoromethyl-Containing Nitrogen Heterocycles
摘要:
A ring-closing metathesis mediated pathway to trifluoromethyl-containing piperidines is detailed. This involves the development of a synthetic route to a new (trifluoromethyl)allylating reagent via a Diels-Alder/retro-Diels-Alder strategy, its application in the synthesis of a series of trifluormethyl-substituted diolefin precursors for ring-closing metathesis, and eventually the successful cyclization of these precursor molecules into the corresponding functionalized piperidines.

A general approach to bicyclic fused pyrrolidines via [3 + 2]-cycloaddition between nonstabilized azomethyne ylide and endocyclic electron-deficient alkenes was elaborated. “Push–pull” alkenes and CF3-alkenes did not react with the azomethyne ylide under the previously reported conditions, and we developed a superior protocol (LiF, 140 °C, no solvent). Among obtained products were medchem-relevant

Ring-closing metathesis(RCM) has been shown to be a viable tool to incorporate fluoride and trifluoromethyl substituents in (hetero)cyclic ring systems. 2-Fluoroacrylamides were cyclized to the corresponding lactams, and trifluoromethyl- substituted olefins were cyclized to yield trifluoromethylated cyclopentenes, pyrrolines and a dihydrofuran derivative.
