Bench-stable and readily accessible allylboronates were utilized in fast and enantioselectiveallylation of cyclic aldimines and ketimines. The N-unsubstituted imine derived from benzaldehyde was generated in situ and directly transformed with the allylationreagent – excess of ammonia was tolerated. All four homoallylic amines could be accessed selectively.

The reactions of chromium-complexed carbenes with 3,3-dimethyl 3H-indoles have been studied in the presence and absence of a Lewis acid as activator in sunlight or under irradiation from a Hg lamp. 1,3-Diazinone-diindolic derivatives have been obtained.
