Abstract

A catalyst system comprising 10 mol % (Pd(OAc) and 20 mol % PPh3 effects the cyclisation of aryl halides onto proximate alkenes via 5-, 6-, and 7-exo-trig, and 7-endo-trig processes giving a variety of bridged-ring carbo- and hetero-cycles in excellent yield. Double bond isomerisation in the product is rarely encountered and may be suppressed by the addition of Tl(1) salts. One example of diastereospecific bis-cyclisation is given and the crystal structure of 1-aza-2-sulphonyl-3,4-benzobicyclo[3.2.1]nona-6-ene is reported.
