A convenient copper-catalyzedcascade cyclization/cyanation reaction for the construction of cyano-containing γ-lactams was developed. The protocol employed TMSCN as the cyano source and proceeded in water under simple conditions. Mechanistic studies indicated this reaction involved an amidyl radical initiated cascade 5-exo-trig cyclization/cyanation process. It is capable of generating a series of

Carbocyclic amines are synthesized efficiently in up to 93% ee by asymmetric ring-closing metathesis (ARCM) with 2-5 mol % chiral Mo complexes. An example is provided where the catalyst is prepared in situ (catalyst isolation not needed) to afford secondary amines that cannot be prepared by alternative methods. [reaction: see text]
