✦ Synopsis
Ring-closing olefin metathesis using the Grubbs catalyst was applied to the cyclisative release of resin-bound sulfonamides. Flexible linkers apparently facilitated the cyclisation-cleavage, allowing a number of novel cyclic sulfonamides to be prepared in good yields using catalytic amounts of the Grubbs catalyst.

The solid-phase synthesis of several g-methyl-substituted-g-butyrolactones using a cyclisation±cleavage reaction is reported. Chemical modi®cations of polymer-bound azido (2a) and iodo alcohols (2b) were realised in order to introduce additional diversity onto the lactone structure.
