Reductive aromatization of quinols: synthesis of the C-arylglycoside nucleus of the papulacandins and chaetiacandin

Org Lett. 2000 Feb 24;2(4):497-9. doi: 10.1021/ol991346l.

Abstract

[reaction: see text] Nucleophilic 1,2-addition of lithiated glycal 9b to functionalized quinone 7 provided, after reductive aromatization, C-arylglycoside 11b. Treatment with mCPBA afforded the tricyclic papulacandin framework. Alternatively, hydroboration gave the chaetiacandin nucleus.
