Synthesis of a Class of Core-Modified Aza-BODIPY Derivatives
摘要:
The convenient synthesis of a new class of conjugated aza-BODIPY derivatives from readily available precursors has been achieved. The new materials bear dose structural similarity to BODIPYs but differ significantly in electronic configuration from known derivatives, leading to markedly different absorption and emission properties.
Microwave assisted copper-free Sonogashira coupling/5-exo-dig cycloisomerization domino reaction: access to 3-(phenylmethylene)isoindolin-1-ones and related heterocycles
摘要:
An efficient microwave assisted one-pot synthesis of substituted 3-(phenylmethylene)isoindolin-1-ones is reported via a copper-free Sonogashira coupling and a regioselective 5-exo-dig cycloisomerization. This domino reaction was also extended to other related heterocycles. (C) 2011 Elsevier Ltd. All rights reserved.

The first syntheses of hybrid structures that lie between subphthalocyanines and subporphyrins are reported. The versatile single‐step synthetic method uses a preformed aminoisoindolene to provide the bridging methine unit and its substituent while trialkoxyborates simultaneously act as Lewis acid, template, and provider of the apical substituent. The selection of each component therefore allows for
