ring-opening of tosylated aziridines under mildphase-transfer catalyzed conditions. High isolated yields coupled with a 1:1 reaction stoichiometry and high levels of relative stereocontrol are distinguishing features of this method. The products are obtained without epimerization, underscoring the optimal conditions afforded by the phase-transfercatalysis for connecting active methylene nucleophiles

A tetrabutylammonium iodide (TBAI)-catalyzed method for synthesis of 2-sulfolmethyl quinolone has been developed. Using water as solvent, a wide range of 2-sulfolmethyl quinolones were obtained in high to excellent yield. In addition, water and TBAI could be reused for five times without significant decrease of the yield of the corresponding product.
