Abstract
In order to access easily to five-membered carbocycles, a new methodology was developed. It involves a sulfonium ylide (instead of carbene, commonly used for this reaction) and a electron poor 1,3-diene. Sulfonium ylides are indeed known to be more easily generated and handled than carbenes. This methodology was applied to various 1,3-dienes and ylides. An asymmetric version of this reaction was also successfully carried out, using chiral sulfonium ylides, leading to excellent enantiomeric excesses.
