Kakei, Hiroyuki published the artcileCatalytic Asymmetric Cyclopropanation of Enones with Dimethyloxosulfonium Methylide Promoted by a La-Li3-(Biphenyldiolate)3 + NaI Complex, Recommanded Product: trimethyloxosulphonium chloride, the publication is Journal of the American Chemical Society (2007), 129(44), 13410-13411, database is CAplus and MEDLINE.
Catalytic asym. cyclopropanation of enones with dimethyloxosulfonium methylide using a La-Li3-(biphenyldiolate)3 + NaI complex is described. The present method is complementary to the previously reported catalytic enantioselective methods in terms of ylides used, and trans products, e.g., I, were exclusively obtained in good yield (96-73%) and high enantioselectivity (99-84% ee). Use of biphenyldiol and NaI additive was essential to achieve high enantioselectivity.
