A "product control via substrate design" strategy has been conceptualized and implemented to harness the potential of aryne and activated alkyne insertions into oxindoles to readily and efficiently furnish pharmacophoric indano- and cyclopentannulated spirooxindole scaffolds in an operationally straightforward, one-pot, transition-metal-free protocol.
Tandem C-2 functionalization-intramolecular Azide-Alkyne 1,3-Dipolar Cycloaddition reaction: A convenient route to highly diversified 9H-Benzo[b]pyrrolo[1,2-g][1,2,3]triazolo[1,5-d][1,4]diazepines

Reactions of Ti(OiPr)4 or Zr(OEt)4 with 4 equivalents of 2,3-dihydro-2,2-dimethyl-7-benzofuranol (ddbfoH) in toluene gave neutral complexes that in the solid state are dimers of [Ti(μ-ddbfo) 2(ddbfo)6] and [Zr(ddbfo)3(EtOH)(μ-EtO)] 2 composition. The former could also be conveniently synthesized in a direct reaction of TiCl4 with ddbfoH. This air-stable aryloxo compound was found to initiate living ring-opening polymerization of lactides affording polyesters with narrow molecular weight distribution. It also catalyzed addition of terminal acetylenes to aryl aldehydes. The Royal Society of Chemistry.
