Abstract
γ-Acetylenic carboxylic acids are cyclized to spirolactones under mild conditions, in the presence of Ag2CO3 catalyst. The corresponding spiro-5-alkylidene-γ-butyrolactones were isolated in high yields, and this process constitutes an easy and efficient route to analogous structures of natural products of biological interest.
