A ring closing metathesis based approach for the spiroannulation of cyclopentanes and cyclohexanes. Formal synthesis of (±)-acorones
Srikrishna,Rao,Gharpure,Babu
, p. 1986 - 1988 (2001)
An efficient ring closing metathesis (RCM) reaction based approach was developed for the spiroannulation of cyclopentanes and cyclohexanes and its utility demonstrated in the formal synthesis of the spirosesquiterpenes acorones.
