Grignard reactions of 4-RC6H4COCHMe(CH2)2CO2Me (I; R = H, Me, F, Cl, Br) with MeCl in anhyd. THF at 60° for 40 min gave 65-81% yield of 0.64-0.70:1 mixts. of δ-lactones II (α-, β-Me; R as before). At 0° the reaction of I (R = F, Cl, Br) gave 38-48% of 0.45-0.51:1 mixts. of II (α-, β-Me; R = F, Cl, Br). The lactones were characterized by 13C and 1H NMR.

Abstract

Grignard reactions of 4-RC6H4COCHMe(CH2)2CO2Me (I; R = H, Me, F, Cl, Br) with MeCl in anhyd. THF at 60° for 40 min gave 65-81% yield of 0.64-0.70:1 mixts. of δ-lactones II (α-, β-Me; R as before). At 0° the reaction of I (R = F, Cl, Br) gave 38-48% of 0.45-0.51:1 mixts. of II (α-, β-Me; R = F, Cl, Br). The lactones were characterized by 13C and 1H NMR.
