The basicities of 2H- and 4H-1,3-benzothiazines (1,2) were measured spectrophotometrically in buffer solutions.The rates of quaternization with methyl iodide were monitored in sealed ampoules by an oscillometric method.The stabilities were determined by m

A method for the synthesis of medium-sized 1,5-benzothiazocines by ring enlargement of 1,3-benzothiazines has been developed. When N-alkyl-1,3- benzothiazines were reacted with dimethyl acetylenedicarboxylate in acetonitrile at room temperature, regioisom
SYNTHESIS AND INVESTIGATION OF 2-OXO- AND 2-THIOXO-1,3-BENZOTHIAZINE DERIVATIVES
Szabo, J.,Varga, I.,Fodor, L.,Bernath, G.,Sohar, P.
, p. 429 - 437 (2007/10/02)
Ring-closure of the 2-mercaptobenzylamine derivatives (10a-d) with phosgene and thiophosgene gave the 7a-d 2-oxo- and the 9a-d 2-thioxo-3,4-dihydro-2H-1,3-benzothiazine derivatives.Other experiments for the preparation of these compounds and analogues are
