Solid-supported heterocumulenes: Preparation and crystal structure of azaaplysinopsins

Annulation of carbodiimides 6a,b, on alumina solid support, selectively gives (Z)-hydantoins 8a,b determined on the basis of X-ray analysis while thermal cyclization affords, after purification, 8a,b with imidazolones 10a,b. In the imidazopyrimidine series, thermal reaction of heterocumulenes 6d yields, via a Dimroth rearrangement, the dipyridoimidazolic compound 11. In all cases, mechanisms for the observed cyclizations have been proposed.
