"On water" catalytic enantioselective sulfenylation of deconjugated butyrolactams

The first catalytic enantioselective α-sulfenylation of deconjugated butyrolactams has been developed using dimeric cinchona alkaloids as catalysts in a water-enriched reaction medium. Highly substituted and densely functionalized γ-lactams, bearing a qua

A convenient new synthesis of 1,2-diarylpyrroles from 3-ethoxycarbonyl-4-oxo-4-phenylbutyraldehyde

An efficient four-step synthesis of ethyl 1,2-diaryl-3-pyrrole carboxylates (4), an isomeric scaffold of pharmacologically active natural products, is reported. The key synthon 3-ethoxycarbonyl-4-oxo-4-phenylbutyraldehyde (3), whose new synthesis is detai

Synthesis of 3-Ethoxycarbonyl-3-buten-4-olides and 3-Ethoxycarbonyl-4-butanolides

This paper describes a synthesis of 3-acyl-2-alkyl-3-ethoxycarbonylpropanoic acids from ethyl 2-oxoalkanoates and 2-bromoalkanoic acids.These acids are cyclised via intramolecular dehydratation to give 2,4-dialkyl-3-ethoxycarbonyl-3-buten-4-olides or are

SYNTHESE DE β-ETHOXYCARBONYL γ-LACTONES

β-ethoxycarbonyl β, γ-insaturated γ-lactones 2 are easily prepared by dehydration of β-acyl β-ethoxycarbonyl α-alkyl propionic acids.Otherwise the condensation of these acids with allylzinc reagents produces β-ethoxycarbonyl γ-lactones 3 with a β-ethyleni

Process for preparing ketones

Ketones are prepared by reacting an aromatic or heterocyclic aldehyde in the presence of a cyanide ion with an unsaturated compound having the formula (I): STR1 wherein R1, R2 and R3 are the same or different and are selected from the group of hydrogen, optionally substituted aliphatic, cycloaliphatic, araliphatic, aromatic, heterocyclic and carboxylic acid ester and R4 is nitrile (CN), --CO--R5 or --CO--OR5 wherein R5 is selected from the group of optionally substituted aliphatic, cycloaliphatic, araliphatic, aromatic and heterocyclic and R1 and R2 and/or R1 and R3 and/or R2 and R5 or R3 and R5 together with the carbon atoms to which they are attached as substituents may also form a carbocyclic or heterocyclic ring. Ketones prepared according to the process of the invention have the formula: STR2 wherein R1 ' and R3 ' are identical or different and are selected from the group of hydrogen, lower alkyl having up to 3 C-atoms and optionally substituted phenyl; and R6 ' is optionally substituted phenyl or a pyridyl.
