Method for preparing coumarino-heteroaromatic ring compounds and derivatives thereof through intramolecular cross-dehydrogenation coupling

The invention relates to a method for preparing coumarino-heteroaromatic ring compounds and derivatives thereof through intramolecular cross-dehydrogenation coupling. Specifically, compounds as shownin a formula Ia is subjected to intramolecular cross dehydrogenative coupling under the catalysis of palladium so as to prepare coumarin-heteroaromatic compounds as shown in a formula I, wherein groups in the formulas are as defined in the specification. The method is mild in reaction conditions, simple to operate, high in atom economy and applicable to a wide range of substrates, and high-yield preparation of multi-functionally substituted coumarin-heteroaromatic compounds and derivatives thereof is realized.

Syntheses of pterocarpenes and coumestans via regioselective cyclodehydration

A highly efficient synthetic route to pterocarpenes and coumestans is described. BCl3-mediated dehydrative cyclization of 1,3-diaryloxyacetones under mild conditions permitted regioselective ring closure to afford 3-((2-iodoaryloxy)methyl)benzo

Hydrogen-atom abstraction/cyclization in synthesis. Direct syntheses of coumestan and coumestrol

The synthesis of coumestrol has been achieved in five steps from 1,3-dimethoxybenzene. The key step is a photochemical cyclization of a glyoxylate ester.
