N-p-Toluenesulfonylpyrroles from 1,3-dienes
Harrington,Sanchez
, p. 175 - 180 (2007/10/02)
1,3-Dienes can be converted to N-p-toluenesulfonylpyrroles in two steps: 1) [4+2]-cycloaddition with N-sulfinyl-p-toluenesulfonamide and 2) conversion of the 3,6-dihydro-1,2-thiazine oxide adduct to a pyrrole using triethylamine-trimethylphosphite.
