Feng, Wei-Xu; van der Lee, Arie; Legrand, Yves-Marie; Petit, Eddy; Dan, Dumitrescu; Su, Cheng-Yong; Barboiu, Mihail published the artcile< Adaptive Encapsulation of ω-Amino Acids and Their Guanidinium-Amide Congeners>, Category: esters-buliding-blocks, the main research area is omega amino acid guanidinium amide adaptive encapsulation.
The binding and the encapsulation of the 6-aminohexanoic acid (1) and 11-aminoundecanoic acid (2) are achieved in aqueous solution and in crystalline Pyrene-box cages. Unexpectedly, the amino-guanidinium AG+ and the amino acids 1 or 2 are reacting in aqueous solution in the absence and in the presence of Pyrene-box cages. The formation of an amide bond between a carboxylic acid and the amino-guanidine unit under mild acidic conditions in water without the use a coupling reagent is extremely interesting and unexpected. The resulted adducts AG1 and AG2 show adaptive binding behaviors and compressions.
Organic Letters published new progress about Amidation. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Category: esters-buliding-blocks.
