## Abstract magnified image A series of __N__βsulfinyl dienophiles **1cβi** has been screened in asymmetric heteroβDielsβAlder reactions using chiral bis(oxazoline)copper(II) and βzinc(II) triflates. The survey pointed out __N__βsulfine **1c** (R ο£Ύ P(ο£ΎO)(OPh)~2~) as the most promising __N__βsulfin

β¦ Synopsis
Benzothiete (1) undergoes cycloaddition reactions with hetero dienophiles with -_ NO or CO-double Eonds, leading to six-membered heterocyclic ring systems of 2H-3,4dih;dro-1,2,3_benzothiadiazine (3_), 4H-3,1,2-benzoxathiazine (4) and 4H-3,1-benzoxathiin. -Studies on the synthesis and the chemical reactivity of benzothiete (1) and its derivatives -
