Sulfonyl bis-N-oxazolidinone (SBO): A new versatile dielectrophile with sequential reactivity

Article abstract of DOI:10.1016/S0040-4039(97)10336-7

The sulfonylbis-N-oxazolidinone (SBO) was designed as a biscarbamoylating reagent Its synthesis was easily carried out starting from sulfuryl chloride, chlorosulfonyl isocyanate or sulfonylbis-isocyanate, using oxazolidinone and/or 2 -haloethanol in one-pot procedures. The structure of SBO was established by X-ray crystallography. The difference of reactivity of both electrophilic carbonyl centers allows the formation of dissymetric linkages.
