Starting from 1,4-dioxaspiro[4,5]decan-8-one and 4-hydroxycyclohexanone, we have synthesized derivatives of tetrahydrobenzofurazan and tetrahydrobenzofuroxan containing a hydroxy or dioxolane group in the 6 position of the ring. We have studied the behavior of the compounds obtained under acid hydrolysis conditions.Novosibirsk Institute of Organic Chemistry, Russian Academy of Sciences, Siberian Branch, Novosibirsk 630090, Russia.
