Modulating dye E(S+/S*) with efficient heterocyclic nitrogen containing acceptors for DSCs

, 2012
Acceptor motifs based on nitrogen containing heterocycles have been synthesized for use in dye-sensitized solar cells (DSCs). Through the selective addition of nitrogen atoms and increased conjugation of the nitrogen containing heterocycles the excited ...

Synthesis of Nitrogen-Containing Heterocycles Through Catalytic Dehydrative Cyclization and Carbon-Hydrogen Oxidative Cycloaddition Reactions

, 2022
The synthetic importance of dehydrative cyclization reactions in the formation of nitrogen-containing heterocycles has been thoroughly documented. Most classical methods require the use of stoichiometric or excess amounts of dehydrating reagents. Here we

Synthesis of 2,3-(Diheterocyclyl)Propanoic Acid Esters as New Building Blocks via Complementary Meldrum’s Acid and Aza-Michael Strategies

Molecules
In this study, we developed two complementary synthetic routes to novel piperidine- and azetidine-containing 2,3-disubstituted propanoic acid derivatives as heterocyclic amino acid building blocks. The strategy employs ketone- and carboxylic acid-derived

l‑(−)-Quebrachitol as a Ligand for Selective Copper(0)-Catalyzed N‑Arylation of Nitrogen-Containing Heterocycles

, 2019
l-(−)-Quebrachitol (QCT) has been found as a ligand of copper powder for selective N-arylation of nitrogen-containing heterocycles with aryl halides. Furthermore, another potential catalytic system (copper powder/QCT/t-BuOK) was successfully adapted to ...
