Abstract
Recently there has been much interest in the diastereoselective manipulation of medium and large ring sys-Recognition of the fact that substituents on such rings can control the conformational preference of the ring system has brought about the use of internal asymmetric induction for construction of macrocyclic natural products. However, general enantioselective routes to conformationally" anchored" medium and large carbocycles are ...
