Cyclo heptenyl

Into this compound, an ethyl radical is introduced at the same C-atom to which the cyclo-heptenyl radical is connected. This Is done, for example. In the following way ... 

As shown by Table 2.1.4.7, the highly enantio-enriched cyclohexenyl and cyclo-heptenyl sulfones 2aa and 2ba, respectively, were obtained in high yields by using Pd(0)/L (1.5 mol%) and BPA (4.5 mol%) (entries 1 and 2). In the case of the eight-membered cyclic carbonate roc-lca the selectivity of the kinetic resolution was so high that even after a prolonged reaction time the conversion of the allylic...
