Synthesis and Selected Transformations of Optically Active Cyclopentenyl Sulfoxides: New Approach o Optically Active Cyclopentenones

Midura W., Krysiak J., Wieczorek M., Filipczak A.

The tandem Michael addition – Horner olefination reaction of (S)- alfa-(diethoxyphosphoryl) vinyl p-tolyl sulfoxide was applied for the synthesis of optically active cyclopentenyl sulfoxides, whichwere converted into the corresponding cyclopentenones by Pummerer reaction with trifluroacetic anhydride. The sequence comprising the tandem Michael – Horner reaction, separation of diastereomers and Pummerer reaction afforded enantiomerically pure substituted cyclopentenones.
