A Transient N−O-Linked Pauson−Khand Strategy for the Synthesis of the Deschloro Carbocyclic Core of the Palau'amines and Styloguanidines
摘要:
A stereocontrolled route to the deschloro cyclopentyl core of the palau'amines and styloguanidines has been developed. This strategy makes use of the intramolecular Pauson-Khand cyclization of an enyne with a "transient N-O tether" to construct a five-membered carbocycle in a diastereoselective fashion.
