Morton, J.,Rahim, A.,Walker, E. R. H.
, p. 4123 - 4126 (1982)
N-(1-p-Toluenesulphonyl-alkyl) amides, which are readily prepared from an aldehyde, an amide and sodium p-toluenesulphinate, are versatile α-amido-alkylating agents for sulphur nitrogen and carbon nucleophiles.
Diastereoselective One-Pot Synthesis of Oxazolines Using Sulfur Ylides and Acyl Imines

This work describes an extended version of the Corey-Chaykovsky reaction to access oxazolines using sulfur ylides and stable precursors of acyl imines. The reaction proceeds through a mixture of aziridines and oxazolines, which provides the trans-oxazolines following in situ Heine-type aziridine ring expansion upon treatment with BF3·OEt2. Following the same one-pot procedure, amidine imides react with the sulfur ylides to provide imidazolines.
A convenient one-pot approach to Paclitaxel (Taxol) side chain via 1,3-dipolar cycloaddition of carbonyl ylides and N-benzoylbenzyl imines

An efficient cascade approach to α-hydroxy-β-amino acid derivatives is reported, which goes through a 1,3-dipolar cycloaddition of carbonyl ylides and N-benzoylbenzyl imines and followed by hydrolysis under acidic conditions. This is the first example of using N-benzoylbenzyl imine as dipolarophile for 1,3-dipolar cycloaddition with carbonyl ylide, which provides a direct and convenient access for the one-pot synthesis of paclitaxel side chain and its derivatives.
