An unusual ring-contraction/rearrangement sequence for making functionalized di- and triquinanes.

Angew Chem Int Ed Engl

Department of Organic Chemistry, Indian institute of Science, Sir C. V. Raman Av., Bangalore 560 012 (India).

Published: October 2014

A novel ring contraction/rearrangement sequence leading to functionalized 2,8-oxymethano-bridged di- and triquinane compounds is observed in the reaction of various substituted 1-methyl-4-isopropenyl-6-oxabicylo[3.2.1]octan-8-ones with Lewis acids. The reaction is novel and is unprecedented for the synthesis of di- and triquinane frameworks.
