Total synthesis of alotaketal A

Org Lett. 2012 Nov 2;14(21):5492-5. doi: 10.1021/ol302570k. Epub 2012 Oct 24.

Abstract

The total synthesis of the cAMP signaling pathway activator (-)-alotaketal A is reported. A convergent approach to the unusual alotane sesterterpenoid skeleton was employed, exploiting a remarkable LiDBB-mediated coupling of an (R)-carvone-derived δ-lactone with an allyl bromide side chain, followed by spiroacetalization.
