Facile synthesis of lactones and dihydronaphthalenes from methyl 2-isobutenyl (or 2-isopentenyl)cinnamates as the common intermediates

We prepared three different types of compounds, two α-alkylidene- γ-butyrolactones and 3,4-dihydronaphthalene-2-carboxylic acid from methyl 2-isobutenylcinnamates or methyl 2-isopentenylcinnamates as the common intermediates, which were derived from the acetates of Baylis-Hillman adducts.

POLARIZED KETENE DITHIOACETALS 63. STEREOSELECTIVE SYNTHESIS OF Α-YLIDENE-Γ-BUTYROLACTONES

A facile method for highly stereoselective synthesis of α-arylidene (4a-d, 4f-h and 4j) and α-ethylidene (4e,4i)-γ-butyrolactones has been developed by acid catalyzed lactonization of the corresponding α-ylidene-γ,δ-unsaturated esters 3a-j.The required es
