Conclusions

  1. 1.

    The action of acid agents on 6, 8-di-tert-butylspiro[4.5]deca-1-oxa-5,8-diene-2,7-dione results in the initial opening of the lactone ring with a retention of the cyclohexadiene structure, and then the isomerization of the thus formed carbonium ion with migration of the carbonium ion center in two directions, and specifically in the six-membered ring and in the side chain.

  2. 2.

    The migration direction of the intermediately formed carbonium ion depends on the temperature.
