, p. 2501 - 2504 (1997)
Enantiomerically pure sultams (+)-4 and (-)-4 were synthesized from tricyclic sultone 1 via a four-step reaction sequence. Their uses as new chiral auxiliaries in asymmetric Diels-Alder reactions with diastereoselectivity up to 94:6 are presented.

An efficient synthesis of prop-1-ene 1,3-sultam 4 and its Diels-Alder reactions is reported. Sultams are also prepared as chiral auxiliaries for asymmetric transformations.
