Lewis acid ( SnC14 ) catalyzed reaction of ethyl a-chloro-a-(p-chlorophenylthio)acetate ( l& ) with several olefins afforded the corresponding ybutyrolactones ('3) in good yields ( 51 -9wo ). Under almost the same conditions, o-(t;butylthio)-o-chloroacetone ( 2 ) reacted with olefins to give the exp

A convenient procedure for the preparation of carbamate derivatives of 5-oxo-2,5-dihydrofuran (3) was described. The method is based on the Michael type addition of three alkyl carbamates (2) with 4-acetyl-5methyl-2,3-dihydro-2,3-furandione (1). According to 1 H nmr spectra of compounds show tautome
