Abstract
An expedient and easy-to-handle synthetic platform has been established for the constructing of 2H-thiophenes carrying fluorine atoms through [4+1] cyclization of enaminothiones with fluorinated carbene precursors. This simple reaction system is well compatible with a wide range of substrates under completely metal-free conditions. The resulting 2H-thiophenes can undergo further late-stage modifications to yield a wide range of fluorine-substituted heterocycles.
期刊介绍:
SYNLETT is an international journal reporting research results and current trends in chemical synthesis in short personalized reviews and preliminary communications. It covers all fields of scientific endeavor that involve organic synthesis, including catalysis, organometallic, medicinal, biological, and photochemistry, but also related disciplines and offers the possibility to publish scientific primary data.
