Pernambucone, a new tropone derivative from Croton argyroglossum.

K P Randau et al.

Die Pharmazie, 64(5), 350-351 (2009-06-18)

Two tropone derivatives, orobanone (1), previously isolated from Orobanche rapum-genistae, and the new natural product pernambucone (3,8-dimethyl-5-isopropyl-2,3-dihydro-1H-azulene-1,6-dione, 2), were isolated from the sterm bark of Croton argyroglossum. The structures were elucidated from spectroscopic data.

Asymmetric synthesis of bicyclo[4.3.1]decadienes and bicyclo[3.3.2]decadienes via [6 + 3] trimethylenemethane cycloaddition with tropones.

Barry M Trost et al.

Journal of the American Chemical Society, 130(45), 14960-14961 (2008-10-22)

The cyanosubstituted trimethylenemethane donor undergoes palladium-catalyzed [6 + 3] cycloaddition with a variety of tropones to yield bicyclo[4.3.1]decadienes in excellent regio-, diastereo-, and enantioselectivity. Products of the Pd-TMM [6 + 3] cycloaddition participate in a thermal [3,3] sigmatropic rearrangement to

An N-heterocyclic carbene-catalyzed [8 + 3] annulation of tropone and enals via homoenolate.

Vijay Nair et al.

The Journal of organic chemistry, 71(23), 8964-8965 (2006-11-04)

A novel protocol for the annulation of tropone to enals involving nucleophilic heterocyclic carbene (NHC) catalyzed homoenolate formation has been developed. Interestingly, the reaction led to bicyclic delta-lactones instead of the expected gamma-spirolactones, presumably by the uncommon [8 + 3]
