Access to the New Isoindolo[1,3]benzothiazocinones via the Combination of N‐Acyliminium Chemistry and Friedel—Crafts Type π‐Cyclization.

Abstract

Access to the New Isoindolo[1,3]benzothiazocinones via the Combination of N-Acyliminium Chemistry and Friedel-CraftsType π-Cyclization. -Synthetic sequences are reported for the short access to isoindolo[1,3]benzothiazocines (V) and their positional. The sequence is extended to the preparation of a chiral derivative (IX). -(CUL, A.; DAICH*, A.; DECROIX, B.; SANZ, G.; VAN HIJFTE, L.; Heterocycles 64 (2004) 33-39; Lab. Chim., Fac. Sci. Tech., Univ.
