                                    A new approach to the synthesis of cyclopenta[g]indole derivatives possessing structural features of natural alkaloids, such as trikentrins and herbindols, is described. The key step in the sequence is a thallium(III)-mediated ring-contraction reaction to transform a cyclohexene moiety into a functionalized cyclopentyl unit.
