And the article contained the following:

This article describes the thermally accelerated organocatalytic α-amination of disubstituted aldehydes with azodicarboxylates under microwave conditions. Compared to the results previously obtained at room temperature, both yield and enantioselectivity could be significantly increased. Employing microwave irradiation resulted in a considerably reduced reaction time. Therefore, this improved protocol allows the fast and efficient synthesis of α,α-disubstituted amino aldehydes and provided the best results for the α-amination of disubstituted aldehydes to date. The experimental process involved the reaction of H-Idc-OH(cas: 79815-20-6).Electric Literature of 79815-20-6

And the article contained the following:

Since the recognition of oligonucleotides as a therapeutic modality, significant work has been devoted to improving therapeutic properties, including nuclease stability. Phosphorothioate (PS) modifications of phosphodiesters are one of the most explored chem. modification and integral to currently approved oligonucleotide therapeutics, including antisense oligonucleotides (ASOs) and short interfering RNAs (siRNAs). Insertion of sulfur into the phosphate bridge in an n-mer leads to 2n isomeric mixtures of PSs, with different nuclease stability and protein-binding properties. Efforts to create stereopure PS-containing oligonucleotides has spurred interest in identifying new synthetic methods. Herein, work on a novel and practical tricyclic PIII chiral auxiliary and its application in solid-supported synthesis of stereopure PS-containing oligonucleotides is reported. The experimental process involved the reaction of H-Idc-OH(cas: 79815-20-6).Product Details of 79815-20-6
