Cyclization of aryl 3-aryl propynoates into 4-arylcoumarins catalyzed by cyclometalated Platinum(II) complexes

Cyclometalated (ppy)PtII complexes (ppy = 2-phenylpyridinato-C2,N) catalyze the intramolecular cyclization of aryl propynoates to form coumarins and benzocoumarins. The complex [(ppy)PtCl(MeCN)] (5 mol %) was the most active and effi

Zeolite-promoted Synthesis of Coumarins and Thiocoumarins

Acidic zeolites, especially faujasites, efficiently promote the intramolecular cyclization of aryl propynoates and propynethioates, which produces coumarins and thiocoumarins, usually in high yields. Comparison with homogeneous Lewis or Br?nsted acids and

Photoinduced cyclization of alkynoates to coumarins with N-Iodosuccinimide as a free-radical initiator under ambient and metal-free conditions

An efficient photoinduced strategy for the preparation of coumarins was developed. In the presence of N-iodosuccinimide (NIS) as a free-radical initiator and under LED (380–385 nm) irradiation and metal-free conditions, the reaction of alkynoates underwen

Regioselective palladium-catalyzed direct cross-coupling of coumarins with simple arenes

An efficient method for the C4-regiocontrolled C-H functionalization of coumarins to enable facile oxidative cross-couplings with simple arene components is disclosed.

Palladium-catalyzed synthesis of 4-arylcoumarins using triarylbismuth compounds as atom-Efficient multicoupling organometallic nucleophiles

Triarylbismuth compounds have been cross-coupled as atomefficient multicoupling organometallic nucleophiles with. 4bromo- and 4- (trifluoromethylsulfonyloxy)coumarins under palladium catalysis conditions. These reactions afforded an array of 4-arylcoumari

Skeletal diversity construction via a branching synthetic strategy

A branching synthetic strategy was used to efficiently generate structurally diverse scaffolds, which span a broad area of chemical descriptor space, and their biological activity against MRSA was demonstrated. The Royal Society of Chemistry 2006.

Formation of coumarins by palladium(II)-catalyzed reaction of phenols with ethyl acrylates

The reaction of phenols with ethyl acrylates in the presence of a Pd(OAc)2 catalyst in trifluoroacetic acid did not yield dihydrocoumarins but gave coumarins, in contrast to the reaction of phenols with propiolates. The addition of K2S2O8 as an oxidant increased the yield of coumarins. The reaction of several phenols with ethyl cinnamate, ethyl crotonate, or ethyl acrylate gave the corresponding coumarin derivatives in moderate to good yields. The coumarin formation competed with the oxidative coupling of electron-rich phenols, which reduced the product yield.

New Method for Preparation of Coumarins and Quinolinones via Pd-Catalyzed Intramolecular Hydroarylation of C-C Triple Bonds

A new and general method has been developed for preparation of coumarins and quinolinones by intramolecular hydroarylation of alkynes. Various aryl alkynoates and alkynanilides undergo fast intramolecular reaction at room temperature in the presence of a
