Abstract: The treatment of substituted ethyl 1-(3’,4’-dihydro-3’,3’-dimethylisoquinolyl)-1-oximinoacetates with hydrazine hydrate leads to a 3,4-dihydroisoquinoline ring enlargement with the annulation of a pyrazole ring to form substituted 5,5-dimethyl-2,3,5,6-tetrahydro- 3-oxopyrazolo[3,4-b]benzo-3-azepines.
