Multicomponent cascade cycloaddition of tropone, allenoate, and isocyanide has been disclosed. This method allows for the rapid construction of a highly unusual tricyclic skeleton in an efficient manner. The proposed transformation proceeds through [8 + 2 + 1] cycloaddition, [1,5]-H shift, and cyclization followed by an alkoxy group migration process.

The AlCl3-promoted cyclization of readily available allenoates with methyleneindolinone is disclosed. The present strategy provides a rapid access to spirocyclic oxindole-cyclohexenones in an efficient manner. Remarkably, the allenoate is implemented as a four-carbon (4C) component to form the ring, which shows high synthetic efficiency. Flexibility of this method allows quick synthesis of spirocyclic oxindole-dihydropyrans by varying one of the components. It is also noteworthy that AlCl3 serves as the chlorine source as well as an effective catalyst to facilitate this interesting transformation.
