SN2 ADDITIONS OF CUPRATES TO SULFONE AND ESTER-POLARIZED CYCLOPENTENYLIC SYSTEMS

The stereochemistry of SN2' addition of cuprates to sulfone and ester-polarized cyclopentenyl systems is shown to depend upon the nature of the leaving group.Allyl ammonium salts usually undergo stereospecific synfacial addition reactions.

AMINE-DIRECTED ADDITION OF CUPRATE REAGENTS TO CYCLOPENTENYL SULFONES

Reaction of cuprate reagents with β'-amino cyclopentenyl sulfones affords bond formation through amine-directed conjugate-addition.Comparison studies with cyclopentenyl sulfone implicate a halocuprate intermediate.
