Significance

Tetronolide is the aglycone of tetrocarcin A, a compound which selectively inhibits the mitochondrial functions of the Bcl-2 family of proteins that serve as apoptosis inhibitors. The synthesis depicted twice uses Diels-Alder reactions to create three of the five rings. A new camphor-derived chiral auxiliary (see structure E) makes its debut. See also: R. K. Boeckman, J. E.
