Аннотация

In this work, new pyrazole derivatives were prepared by one-pot three-component reaction emloying symmetric and asymmetric 1,2-disulfonylhydrazines, cyclohexyl isocyanide, and dialkyl acetylenedicarboxylates. Reactions with asymmetric 1,2-disulfonylhydrazines led to two regioisomers, which were distinguished by density functional theory calculations and the major isomer attributed to the energically more stable one.
