Stereoselective synthesis of activated 2-arylazetidines via imino-aldol reaction.
A simple and efficient synthetic route to substituted N-sulfinyl and N-sulfonyl azetidines is described involving imino-aldol reaction of ester enolates with racemic and non-racemic aldimines for obtaining β-amino esters as a key step. These β-amino esters on subsequent reduction followed by TsCl/KOH mediated cyclization produced the corresponding racemic and non-racemic azetidines with high yi...
متن کاملOrganic Synthesis: Aldol Condensation Reaction
In an "aldol addition" reaction an enol or enolate of an aldehyde or ketone reacts with a second aldehyde or ketone forming a new carbon-carbon bond which makes the aldol reaction an important reaction for organic synthesis. Originally, the aldol reaction used ethanal (see below) and therefore the product contained both an aldehyde and an alcohol functional group; thus it became known as the al...

متن کاملAsymmetric aldol reaction via memory of chirality.
Asymmetric aldol reactions of α-amino acid derivatives via memory of chirality were developed. Chiral oxazolidones with contiguous tetra- and trisubstituted chiral centers were obtained in 78-94% ee by the asymmetric aldol reaction followed by intramolecular acylation.
متن کاملApplication of Green Procedure for the Synthesis of Substituted Pyrroles: Multi-component Reaction of Oxalyl Chloride
A novel, convenient and efficient approach to synthesis of pyrrole derivatives via the reaction of primary amines, alkyl propiolates and oxalyl chloride is described. The method offers several advantages including high yields of products and performing reaction in water as the solvent.
