Abstract
Source of material : To a mixture of 3-phenyl-3,6-dihydro-1,2-dioxine (0.6 g) in dichloromethane (5 ml) under a nitrogen atnoosphere at ambient temperature was added benzyl l^-(triphenylphosphoranylidene)acetate ( 1.53 g). After 3 days the mixture was concentrated and subjected to column chromatography. Elution with a mixture of hexane/ethyl acetate (7:3) afforded the title compound in 83% yield as a white solid. Recrystallisation from an heptane solution gave colorless crystals with mp 317 К 318 K. The substituents occupy trans positions about the cyclopropyl ring and the conformation is almost identical to that found in the related structure with a methyl group at the C3 position (cis to C4); see ref. 1.
