Substrate-selective dehydrocondensation at the interface of micelles and emulsions of common surfactants
Scratch the surface: Dehydrocondensations between carboxylates and amines by using an amphiphilic 1,3,5-triazinylammonium-based coupling agent were accelerated by the interfacial effect of micelles and emulsions of common surfactants (see figure). The reaction of carboxylates was promoted by both anionic and nonionic surfactants, and that of amines was promoted by only a nonionic surfactant. High selectivities for more lipophilic substrates were observed in micelles or emulsions. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim

Phototriggered Dehydration Condensation Using an Aminocyclopropenone
金沢大学新学術創成研究機構A phototriggered dehydration condensation using an aminocyclopropenone has been developed. The UV irradiation of an aminocyclopropenone generated a highly reactive ynamine in situ and the dehydration condensation of a carboxylic acid and an amine coexisting in the reaction solution smoothly proceeded to afford an amide. This reaction is completely controllable by the ON/OFF states of a UV lamp. © 2017 American Chemical Society.Embargo Period 12 month
Convenient modular method for affinity labeling (MoAL method) based on a catalytic amidation
金沢大学医薬保健研究域薬学系A modular methodology for affinity labeling, in which three essential elements generally constituting affinity probes are prepared separately as individual molecules, has been developed based on a catalytic amidation. © 2009 The Royal Society of Chemistry
