Phosphorus 2-pyrone derivative and preparation method thereof

摘要

Provided are a novel phosphorus 2-pyrone derivative and a preparation method thereof. The phosphorus 2-pyrone derivative according to the present invention is capable of being efficiently synthesized by treating an alkyl hydrogen alkynylphosphonate derivative and an alkyne derivative with a minimal amount of a gold catalyst.
