A tandem strategy for the construction of benzofuran motifs has been developed directly from gem-dibromoalkenes and phenols under palladium-catalyzed conditions.
已经开发了一种从gem-二溴代烯烃和酚直接在钯催化条件下构建苯并呋喃基团的串联策略。

The present invention provides compositions and methods for preventing, treating, or inhibiting inflammatory diseases, disorders, or conditions of the skin, and diseases, disorders, or conditions associated with collagen depletion using one or more estrogenic agents.
2-phenylbenzo[b]furan glycosides could promote estrogen biosynthesis. To find high active 2-phenylbenzo[b]furans, fifty-four 2-phenylbenzo[b]furans were prepared via four strategies according to corresponding substrate scopes. Biological evaluation in HEK293A cells showed that some compounds exhibited promotive activity on estrogen biosynthesis. 2-(4-Chlorophenyl)-7-methoxybenzo[b]furan possessed the

A copper-catalyzed decarboxylative intramolecular CâO coupling reaction was established. Under aerobic conditions in the presence of cupric chloride/1,10-phenathroline, a variety of 2-arylbenzofurans were prepared from 3-arylcoumarins in one-pot with yields from 26% to 84%.
