## Abstract magnified image A series of __N__‐sulfinyl dienophiles **1c‐i** has been screened in asymmetric hetero‐Diels‐Alder reactions using chiral bis(oxazoline)copper(II) and ‐zinc(II) triflates. The survey pointed out __N__‐sulfine **1c** (R P(O)(OPh)~2~) as the most promising __N__‐sulfin

N-Iklethyldithiophthalimide serves as a very reactive dienophile and reacts with 1,3-dienes at room temperature to give Diels-Alder products in very high rqioselectivity.
Enantioselective hetero Diels-Alder (HDA) reactions of 1,3-cyclohexadiene with benzyl N-sulfinylcarbamate 1a and with N-sulfinyl-p-toluensulfonamide 1b promoted by chiral Ti(IV)-based Lewis acids are reported. The obtained yields and enantiomeric excesses obtained are heavily dependant on the mode o
