资源简介：
A general
method for highly functionalized 2-pyrones via a base-mediated
sequential vinylogous addition and cyclization of γ-phosphonyl/sulfonyl
crotonates and ynones are described. An exclusive E-geometry with
respect to the newly generated olefin substituent at C3 of pyrone
was observed. Imino glyoxalates and glycine imines similarly reacted
with ynones to deliver 3-imino pyrones.
