CeO2-catalyzed direct synthesis of dialkylureas from CO2 and amines

CeO2 showed higher activity for the direct synthesis of 1,3-dibutylurea (DBU) from CO2 and n-butylamine than the metal oxides tested. The solvent largely influenced the reaction over CeO2, and N-methylpyrrolidone (NMP) was preferable among various solvents tested from the viewpoints of activity and selectivity. The catalyst system composed of CeO2 catalyst and NMP solvent (CeO2 in NMP) was applicable to the reactions of various amines such as linear primary alkylamines or branched primary alkylamines, although tert-butylamine afforded low conversion. In contrast, secondary amines and aniline provided no yield of the ureas. The combination of 2-cyanopyridine with CeO2 in NMP (CeO2 in NMP with 2-cyanopyridine) promoted the transformation of the unreactive amines, showing that tert-butylamine and aniline were converted to the corresponding ureas in 82% and 80% yields, respectively. These yields are much higher than those reported in the previous literatures, indicating that CeO2 in NMP with 2-cyanopyridine drastically promoted transformation of amines with low reactivity.

Copper(I)-Catalysed Multicomponent Reaction: Straightforward Access to 5-Hydroxy-1H-pyrrol-2(5H)-ones

A copper-catalysed multicomponent coupling reaction between readily available (Z)-3-iodoacrylic acids, terminal alkynes, and primary amines was developed to smoothly access a small library of 5-hydroxy-1H-pyrrol-2(5H)-ones in good yields. This practical and general process was applied to a short-steps synthesis of the natural product pulchellalactam.

New synthesis of vanillin by degradation of lignin in presence of functional basic ionic liquid

The degradation of lignin catalyzed by functional basic ionic liquid was investigated. Higher conversion of lignin and simpler degradation product composition were obtained in the presence of basic ionic liquid, comparing with that under traditional NaOH
