摘要：
Dianion 2 derived from N-Boc-aminobenzotriazole 1 condenses in a [1.2]-fashion with alpha,beta-unsaturated aldehydes; subsequent oxidation of the resulting allylic alcohols 7 using manganese(IV) oxide or, less effectively, treatment of the derived acetates 10 with Pd(0), results in direct formation of the novel triazolo[1,2]benzodiazepines 9 and 11 by intramolecular addition of the pendant amino group.
