Heterocyclic Structure

A compound that reproduces the acute renal proximal tubular necrosis associated with ingestion of Isotropis forrestii, by animals, has been isolated from the plant. The novel heterocyclic structure was determined by a single-crystal X-ray diffraction study. The spectroscopic data are presented and rationalized with respect to the assigned structure.

The thermal treatment of [Ru2(CO)6(μ-η1,η2-C4H3O){μ-P(C4H3O)2}] 1 with dimethyl acetylenedicarboxylate (DMAD) at 110 °C leads to cyclotrimerization of DMAD. The cyclotrimerization product hexamethyl benzenehexacarboxylate, [C6(COOCH3)6] 2, was obtained in 37% yield and characterized by a combination of spectroscopic data and single crystal X-ray diffraction study. Compound 2 crystallizes in the monoclinic space group P1bar with a = 10.3002(12), b = 11.0371(13), c = 18.781(2) Å, α = 76.148(2), β = 87.390(2), γ = 74.001(2)°, Z = 4 and V = 1992.2(4) Å3.

Alder Adduct

The structure of the compound obtained on heating the naturally occurring clerodane furanoditerpene (1) had been formulated as (2) on the basis of spectroscopic studies. A single-crystal X-ray diffraction study on the dihydro derivative of (2) has confirmed this and provides support for the stereochemistry previously assigned to (1) on the basis of chemical evidence.
