A rapid, asymmetric synthesis of the Decahydrofluorene core of the hirsutellones


Tilley, S David; Reber, Keith P; Sorensen, Erik J (2009). A rapid, asymmetric synthesis of the Decahydrofluorene core of the hirsutellones. Organic Letters, 11(3):701-703.

Abstract

A tandem ketene-trapping/Diels-Alder cyclization sequence was the pivotal transformation in an efficient, asymmetric synthesis of a decahydrofluorene tricyclic structure possessing eight stereogenic centers and key features of the hirsutellone class of antitubercular natural products. The hirsutellone-like beta-keto ester that was fashioned by this sequence (13 steps; 6% overall yield) demonstrated significant inhibitory activity against Mycobacterium tuberculosis. The mechanism of action of this antitubercular compound is not yet known.
