چکیده

We discovered a novel organocatalysed multicomponent domino Knoevenagel-aza-Michael-cyclocondensation reaction leading to an unprecedented straightforward synthesis of 1,5-diazabicyclo[3.3.0]octane-2,6-diones. The specific capability of the (DHQ)2PHAL organocatalyst in this process was also highlighted to eventually furnish the corresponding bicyclopyrazolidinones with up to 96 : 4 er.

Organocatalysed decarboxylative protonation process from Meldrum's acid: enantioselective synthesis of isoxazolidinones.

An asymmetric organocatalysed decarboxylative protonation reaction allowed a straightforward synthesis of α-substituted isoxazolidin-5-ones from readily available 5-substituted Meldrum's acids. This process is initiated by an anionic formal (3+2) cycloaddition-fragmentation, generated in-situ from a sulfone-amide precursor which also served as a latent source of proton.

Multicomponent decarboxylative allylations.

The reaction of Meldrum's acid, pyrrolide, and allyl carbonates allows a multicomponent decarboxylative coupling to form allylated acyl pyrroles. This strategy is made possible by the in situ formation of β-oxo carboxylates from Meldrum's acid. Subsequent decarboxylative enolate formation and electrophilic allylation complete the reaction. Addition of benzylidene malononitriles as good Michael ...

Infrared Assisted Production of 3,4-Dihydro-2(1H)-pyridones in Solvent-Free Conditions

A green approach for the synthesis of a set of ten 4-aryl substituted-5-alcoxy carbonyl-6-methyl-3,4-dihydro-2(1H)-pyridones using Meldrum's acid has been devised, the absence of solvent and the activation with infrared irradiation in addition to a multicomponent protocol are the main reaction conditions. The transformations proceeded with moderated yields (50-75%) with a reasonable reaction ra...

Nano-ZnO Catalyzed Multicomponent One-Pot Synthesis of Novel Spiro(indoline-pyranodioxine) Derivatives

A simple catalytic protocol for the synthesis of novel spiro[indoline-pyranodioxine] derivatives has been developed using ZnO nanoparticle as an efficient, green, and reusable catalyst. The derivatives are obtained in moderate to excellent yield by one-pot three-component reaction of an isatin, malononitrile/ethylcyanoacetate, and 2,2-dimethyl-1,3-dioxane-4,6-dione in absolute ethanol under con...
