Chemical utilization of carbon dioxide (CO2) has emerged as a sustainable access for synthesizing high-value chemicals. Continuously designing the more practical reaction systems is large importance. Herein, an unprecedented and powerful copper-PMHS reductive system o-aminobenzamides with CO2 disclosed. Synthetically, diverse range quinazolinones (>70 examples) are rapidly assembled excellent functional group tolerance in good yields. Moreover, building other types heterocycles such benzothiazoles benzimidazoles also allowable. Mechanistically, differing from reported carbonylation cases, this finding represents scarce example single-carbon atom synthon PMHS system.

A phosphine-catalyzed three-component cyclization reaction between anilines, carbon dioxide, and chloroalkanes was developed for the synthesis of oxazolidinones. This strategy not only proceeds under ambient CO2 pressure metal-free condition but also shows a broad substrate scope, including aromatic amines, aliphatic chiral amino acid esters, bioactive molecules, providing an efficient environmentally benign route to synthesize pharmaceutically relevant N-aryl-oxazolidinones. Mechanistic investigations utilizing mass spectrometry (MS) indicate involvement multiple phosphine intermediates in this process, thereby elucidating underlying mechanism. Moreover, relationships these Tolman cone angles or solvent effect phosphines were examined through spectrometry.

The use of CO2 as a C1 building block is great relevance and focus current research. Herein we report the synthesis air-stable internal phosphonium salts their application catalysts in N-methylation N-formylation amines utilizing CO2. A series were prepared tested for these valuable transformations. Under optimized reaction condition, was achieved at 23 °C, 1 bar pressure under solvent-free conditions using equimolar amounts n-hexylsilane reducing agent. modification led to selectivity switch, realized 70 °C acetonitrile same catalyst reductant. In total, 22 converted corresponding N-methylated products up 99% yield. Moreover, 25 examples conversion N-formylated 96% yield are reported. Both reactions can be performed large scale. also applied late-stage functionalization pharmaceutical sertraline. NMR studies control experiments revealed two different pathways intermediates N-formylation.
