Pyranophane Transannular Diels-Alder Approach to (+)-Chatancin: A Biomimetic Asymmetric Total Synthesis

Soucy, Pierre,L'Heureux, Alexandre,Toro, Andras,Deslongchamps, Pierre

, p. 9983 - 9987 (2007/10/03)

An asymmetric total synthesis of (+)-chatancin was achieved via a transannular Diels-Alder (TADA) reaction of an in situ generated macrocyclic pyranophane pseudobase. The presented route constitutes the second of two proposed biosynthetic pathways that in
