Synthesis and Reactions of Phosphoryl-Substituted Sulfines

The synthesis of a variety of phosphoryl-substituted sulfines 5 by the reaction of α-silyl carbanions with sulfur dioxide is described.For characterization purposes the prepared sulfines were converted into their cycloadducts 6 with 2,3-dimethyl-1,3-butad

A SHORT SYNTHESIS OF THE Δ1-CARBOPENEM RING SYSTEM

Michael addition of N-lithio-4-vinyl-azetidin-2-one to several vinyl phosphonates gave adducts which were converted to Δ1-carbopenems via ozonolysis and an intramolecular Horner-Wittig reaction.
