Stereoselective synthesis of Heliannuol G

The first stereoselective synthesis of Heliannuol G has been achieved employing an o-quinone methide intermediate. The present synthesis triumphs over all the drawbacks associated with the reported one and reveals an impressive overall yield of 12.37%.

Biomimetic Total Synthesis of Paeoveitol

A highly stereocontrolled synthesis of paeoveitol has been developed in 26% yield, in 7 steps from commercially available materials. The synthetic strategy was inspired primarily by the biogenetic hypothesis and was enabled by hetero-Diels-Alder cycloaddi

SAR studies of epoxycurcuphenol derivatives on leukemia CT-CD4 cells

Bioactive natural products are a potential source of new pharmaceuticals since they offer new modes of action and more specific activities. The use of derivatization also enables the optimal structure for their biological activity to be determined. In thi

Synthesis of heliannane skeletons. Facile preparation of (±)-heliannuol D

Heliannuol D is a natural product with a 7,10-heliannane skeleton, isolated from Helianthus annuus. It has been synthesized in eight steps, in good yield, using a new biomimetic method. Key steps were a Fries rearrangement, a Grignard reaction and, finall

Synthesis of O-methyl epi-heliannuol E

A synthesis of the methyl ether of an epimer of the alleochemical heliannuol E is described. The route involves indium mediated allylation of a benzopyranone carboxylate and subsequent one carbon degradation to a vinyl group.

First total synthesis of (±)-helibisabonol A

Helibisabonol A is a new sesquiterpene with phytotoxic activity isolated from Helianthus annuus leaves. (±)-Helibisabonol A has been synthesized as an approach to the natural product in the search for new herbicide models. Herein, we report the first tota

2-Hydroxy-5-allyloxyacetophenone (Ia), on Claisen condensation with ethyl formate in the presence of sodium yielded 2-hydroxy-2,3-dihydro-6-allyloxychromone (IIa), which on dehydration and Claisen rearrangement gave 5-allyl-6-hydroxychromone (IVb).Cycliza

Photochemical Dimerization of 2-Acyl-1,4-benzoquinones in the Presence of Rose Bengal

Irradiation of 2-acyl-1,4-benzoquinone 1 in the presence of rose bengal afford the quinone dimer 2-acyl-3-(3-acyl-4-hydroxyphenoxy)-1,4-benzoquinone 2 in good yields.This type of dimer was quite different from another dimer 3, which was obtained in the photoreaction of 2-acyl-1,4-benzoquinone 1 in the absence of rose bengal.In this photoreaction in the presence of rose bengal, the excited state of rose bengal played a very imprtant role.However, singlet oxygen generated by rose bengal sensitization is not involved in the photodimerization reaction of quinones.On the other hand, 2-acyl-1,4-benzoquinone 1 can quench the rose bengal sensitized photooxygenation of α-pinene and simultaneously dimerize to give the same dimer 2 mentioned above.In addition, photolysis of the acylquinoline 1 in a heterogeneous system using rose bengal coated silica gel as sensitizer also afford the same dimer obtained in the homogeneous system in comparable yields.
