چکیده
THE TITLE COMPOUND [SYSTEMATIC NAME: (E)-2-hy-droxy-5-(phenyl-diazen-yl)cyclo-hepta-2,4,6-trien-1-one], C(13)H(10)N(2)O(2), is essentially planar with an r.m.s. deviation of 0.036 (2) Å and a dihedral angle of 1.57 (8)° between the phenyl and tropolone rings. In the crystal, mol-ecules are linked by pairs of O-H⋯O hydrogen bonds into inversion dimers. The dimers are further connected by C-H⋯O hydrogen bonds and π-π stacking inter-actions, with centroid-centroid distances of 3.6934 (9) and 3.6282 (9) Å.

Novel retinoidal tropolone derivatives. Bioisosteric relationship of tropolone ring with benzoic acid moiety in retinoid structure.
Several tropolone derivatives (4-7) were designed as novel retinoids on the assumption that the tropolone ring may mimic the benzoic acid moiety in retinoid structures, such as Am80 (2). Among the synthesized compounds, 5-[2-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthyl)ethynyl]tropolone (7a) showed moderate potency as a differentiation-inducer of HL-60 cells. The activities of the tropolo...

In the title compound, [Rh(C(22)H(32)N(3)O(5))(CO)(2)], the Rh(I) atom is coordinated by two carbonyl ligands and two tropolonate O atoms in a distorted square-planar geometry. It is an example of a new type of tropolone derivative that has not been characterized via solid-state methods. Weak intra-molecular C-H⋯N and inter-molecular C-H⋯O hydrogen bonds, and π-π stacking inter-actions between ...

متن کاملGenetic, molecular, and biochemical basis of fungal tropolone biosynthesis.
A gene cluster encoding the biosynthesis of the fungal tropolone stipitatic acid was discovered in Talaromyces stipitatus (Penicillium stipitatum) and investigated by targeted gene knockout. A minimum of three genes are required to form the tropolone nucleus: tropA encodes a nonreducing polyketide synthase which releases 3-methylorcinaldehyde; tropB encodes a FAD-dependent monooxygenase which d...
