Alkylation of 2H-1,2,3-benzothiadiazine 1,1-dioxide and its aromatic ring substituted derivatives was studied in detail. It was found that alkylation took place both at N(2) and N(3) atoms. In the latter case, a series of interesting mesoionic compou

Based on the 13C NMR chemical shifts of more than 300 oxindole derivatives, substituent-induced chemical shifts have been calculated for this family of compounds. These substituent effects have been compared to those of monosubstituted benzenes and t

The configuration and the conformation of two trifluoromethyl-triaryl-ethane diastereomer pairs and of some sole isomers were determined using the through-space spin-spin coupling between fluorine atoms and the hydrogen of the hydroxyl group. The mol

Highly stereoselective eliminations were achieved by acid-catalysed dehydration of 1-(4-alkoxy)-3,3,3-trifluoro-1,2-diphenylpropan-1-ols (10, 11, 15). The influence of the trifluoromethyl group on the stereochemistry of the elimination has been discu

A unique, regioselective 7-methylation reaction has been discovered during the reductive 3-alkylation of isatin with i-BuOH at 230 °C, in the presence of Raney nickel, under hydrogen atmosphere. Based on this observation, a synthetic method has been
