Carbopalladation of thioketals [I; X, X1 = S, O; X = X1 ?O; m, n = 1, 2; R = CH(CO2Me)2, OMe, CH(COMe)CO2Et, etc.;] with Li2PdCl4 and RNa gave cyclic intermediates II with new regiospecific C-C bonds as a result of long-range regiocontrol by S atoms. PrS(CH2)3 CH=CH2 formed similar cyclic intermediate.
