摘要：

The rhodium(II)-catalysed cyclisation of acyclic alpha-diazomalonate 1b and alpha-diazo-beta-keto esters 1c, d give stereoselectively the highly substituted delta-lactone 3b and cyclohexanones 3c, d, respectively, by [2,3]sigmatropic rearrangement via the stereocontrolled nine-membered allylsulfonium ylides 2b-d.
