An expedient access to optically active spiro-[butyrolactone-pyrrolidine] was successfully developed via an unprecedented Cu(I)-catalyzed exo-selective 1,3-DC of azomethine ylides with α-methylene-γ-butyrolactone, which exhibited high diastereoselectivity (>98 : 2), excellent enantioselectivity (96->99% ee) and a broad substrate scope under mild conditions.

(+) and (-) alpha-methylene-hexahydrobenzofuranone derivatives with a stereochemically pure cis ring junction were used as models of sesquiterpene lactones to study their photoreactivity toward thymidine. After 313 nm irradiation of a deoxygenated acetone solution of lactone models and thymidine, six

The synthesis of a series of alpha-methylene-gamma-butyrolactones (compounds 4a, 4b, 6-12, 16, 17) and alpha,beta-unsaturated-delta-lactones (compounds 19-23, 25, 26) starting from 4,4-dimethyldihydrofuran-2,3-dione (1) has been described. Their chemical structures were assigned by spectroscopic evidence. These new compounds exhibited significantly different

A zinc or indium-mediated Barbier-type allylation of aldehydes with 3-bromomethyl-5H-furan-2-one in aqueous solvents was developed to provide an efficient route to α-methylene-γ-butyrolactone, which is synthetically very useful. The desired products were obtained in moderate to high yields in aqueous solvents.
