Abstract: <img src='/image/spc_char/gamma.gif' border=0>-Methyl-<img src='/image/spc_char/alpha.gif' border=0> -(alkylidene substituted)-<img src='/image/spc_char/gamma.gif' border=0>-butyrolactones have been synthesized in two steps. The anion of allyl phos­phonate <b style="">1</b> is condensed with different carbonyl compounds to afford <img src='/image/spc_char/alpha.gif' border=0>,<img src='/image/spc_char/beta.gif' border=0>-unsaturated esters <b style="">2a-g</b>which are cyclised using 6<i style="">N</i> HCl to give title compounds.
