Decarboxylative Intramolecular Arene Alkylation Using N-(Acyloxy)phthalimides, an Organic Photocatalyst, and Visible Light

An intramolecular arene alkylation reaction has been developed using the organic photocatalyst 4CzIPN, visible light, and N-(acyloxy)phthalimides as radical precursors. Reaction conditions were optimized via high-throughput experimentation, and electron-rich and electron-deficient arenes and heteroarenes are viable reaction substrates. This reaction enables access to a diverse set of fused, partially saturated cores which are of high interest in synthetic and medicinal chemistry.

Tandem Oxidative Ring-Opening/Cyclization Reaction in Seconds in Open Atmosphere for the Synthesis of 1-Tetralones in Water-Acetonitrile

A mild and practical tandem oxidative ring-opening/cyclization reaction mediated by Ce4+ for the synthesis of 1-tetralones is presented. This rapid transformation was completed within 30 s and conducted in an open reactor at 0 °C in a water-acetonitrile mixture. Various cyclobutanol derivatives are transformed into desired products in good to high yields, and this reaction can be easily scaled up to the gram scale.

Cyclopenteno[b]pyridine derivatives

The invention relates to novel cyclopenteno[b]pyridine derivatives which have a group X on the 7-position and related tricyclic compounds. X is CONHR3, or CO2 R5 wherein R3 is hydrogen or lower alkyl and R5 is hydrogen or a lower alkyl or lower aralkyl group which may be substituted by alkyl, alkoxy, halogen, nitro or trifluoromethyl; other substituents may be present. The compounds are intermediates for compounds wherein X is CSNHR3 which are anti-ulcer agents.
