Regioselective deprotonation of 3-chloro-1-tosylpyrrole is used to prepare the 2-formyl derivative. Application of this chemistry in a synthesis of the left hand pyrrolo-furan substructure of roseophilin is described.

Abstract 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.
Regioselective deprotonation of 3-chloro-1-tosylpyrrole is used to prepare the 2-formyl derivative. Application of this chemistry in a synthesis of the left hand pyrrolo-furan substructure of roseophilin is described.
