Abstract

A straight forward synthesis of the 1,4,2‐benzodithiazine system bearing an ester functionality as potential inducers of systemic acquired resistance in plants was developed utilizing the ring expansion reaction of 1,3‐benzodithioles. The structure of the isomers obtained was established using x‐ray diffraction. The reactivity of the products towards activated alkynes and ring contraction reactions in the presence of base is discussed.

## Abstract magnified image A new simple synthetic approach to 2,4‐difuryl‐4__H__‐3,1‐benzothiazines from 2‐isothiocyanoaryldifuryl‐methanes in the presence of acidic catalyst is described. This rearrangement is a new example of furan ring migration reaction resulting from intramolecular attack wi
