3-Amino­benzoic acid–4-nitro­benzoic acid (1/1)

In the title 1:1 adduct, C7H5NO4·C7H7NO2, the nitro group of the 4-nitro benzoic acid is twisted from the attached ring by 4.40 (8)°. In the crystal, the mol­ecules are linked into ribbon-like structures along [150] and [10] via O—H⋯O, N—H⋯O, N—H⋯N and C—H⋯O inter­molecular hydrogen bonds

Total Synthesis of Ramonanins A–D

The first total synthesis of the ramonanin family of lignan natural products is described. The short synthesis involves a 2,5-diaryl-3,4-dimethylene tetrahydrofuran intermediate, which participates in an unexpectedly facile Diels-Alder dimerization, generating all four natural products. Insights into the reactivity and stereoselectivity of the key dimerization are provided through computational studies employing B3LYP/6-31G(d) and M06-2X/6-31G(d) model chemistries.This work was supported by the Australian Research Council and a Marie Curie Career Integration Grant.
