One-Pot Synthesis of 3-Substituted 3,4-Dihydro-1,2,3-benzotriazine Derivatives Based on the Reaction of o-Bromobenzyl Azides with Butyllithium
An efficient one-pot procedure for the preparation of 3-substituted 3,4-dihydro-1,2,3-benzotriazines 2, 3, and 4 from o-bromobenzyl azides 1 is described. The reaction of these azides with BuLi in THF at -78 generates o-lithiobenzyl azides via the Br/Li e

Efficient synthesis of substituted 3-acyl-3,4-dihydrobenzo[d][1,2,3]triazines
Acylated o-triazenylbenzylamines were cyclized to give 3-acyl-3,4-dihydrobenzo[d][1,2,3]triazines in good yields. Thus, a novel cyclization via a Jacobsen indazole-type reaction to aminoindazoles is observed in this context.
