Sone, Toshihiko published the artcileCatalytic asymmetric synthesis of 2,2-disubstituted oxetanes from ketones by using a one-pot sequential addition of sulfur ylide, Safety of trimethyloxosulphonium chloride, the publication is Angewandte Chemie, International Edition (2009), 48(9), 1677-1680, database is CAplus and MEDLINE.
Enantiopure 2-Me-2-R-substituted oxetanes (R = n-octyl, 9-decenyl, cyclohexyl, Ph, 4-ClC6H4, 4-FC6H4, PhCH2CH2, 2-naphthyl) were synthesized from the corresponding ketones RCOMe and dimethyloxosulfonium methylide via one-pot double methylene transfer catalyzed by a heterobimetallic La/Li complex. Chiral amplification in the second step was the key to obtain oxetanes in high enantiomeric excess.
