Carboxylative cyclization of substituted propenyl ketones using CO2: Transition-metal-free synthesis of Α-pyrones

Carbon dioxide is a green carboxylative reagent due to its non-toxic and renewable properties. Described herein is a carboxylative cyclization of substituted 1-propenyl ketones via γ-carboxylation using CO2, which provides an efficient, transit

Reactions of β-(4-Methoxyphenyl)glutaconic Anhydride with Phenolic Ethers: Synthesis of Substituted δ-Hydroxy-α,γ-pentadienoic Acid δ-Lactones and Related Compounds

Condensation of β-(4-methoxyphenyl)glutaconic anhydride (I) with phenetole under Friedel-Crafts conditions furnishes δ-(4-ethoxyphenyl)-δ-hydroxy-β-(4-methoxyphenyl)-α,γ-pentadienoic acid δ-lactone (IIa) and γ-(4-ethoxybenzoyl)-β-(4-methoxyphenyl)crotonic acid (IIIa).A similar condensation of I with diphenyl ether results in the formation of δ-hydroxy-β-(4-methoxyphenyl)-δ-(4-phenoxyphenyl)-α,γ-pentadienoic acid δ-lactone (IIb) and β-(4-methoxyphenyl)-γ-(4-phenoxybenzoyl)crotonic acid (IIIb).Some reactions of II and III have been studied.
