Chemical engineers ensure the efficiency and safety of chemical processes, adapt the chemical make-up of products to meet environmental or economic needs, and apply new technologies to improve existing processes. 38002-45-8, Name is (3-Bromoprop-1-yn-1-yl)trimethylsilane, molecular formula is C6H11BrSi, Formula: https://www.ambeed.com/products/38002-45-8.html, belongs to naphthyridine compound, is a common compound. In a patnet, author is Song, Geunmoo, once mentioned the new application about 38002-45-8.
Two indolocarbazole-naphthyridine foldamers 2 and 3 that fold into helical conformations were prepared. The 4-(N,N-dimethylamino)pyridine (DMAP) moiety was introduced at one end of the foldamer strands to develop foldamer-based catalysts for the site-selective acylation of polyols. These foldamers adopt helical conformations containing internal cavities capable of binding octyl beta-d-glucopyranoside. The association constants were determined to be 1.9 (+/- 0.1)x10(5) M-1 for 2 and 2.1 (+/- 0.1)x10(5) M-1 for 3 in CH2Cl2 at 25 degrees C. In the presence of DMAP, 2 or 3 as the catalysts, octyl beta-d-glucopyranoside was subjected to acetylation under identical reaction conditions. The DMAP-catalysed reaction afforded the random distribution of the monoacetylates (6-OAc : 4-OAc : 3-OAc : 2-OAc=33 : 24 : 41 : 2). In contrast, foldamers 2 and 3 led to the predominant formation of 6-OAc. The relative distributions were estimated to be 6-OAc : 4-OAc : 3-OAc=88 : 4 : 6 : similar to 0 with 2 and 6-OAc : 4-OAc : 3-OAc : 2-OAc=90 : 3 : 6 : 1 with 3.
Future efforts will undeniably focus on the diversification of the new catalytic transformations. In my other articles, you can also check out more blogs about 38002-45-8. Formula: https://www.ambeed.com/products/38002-45-8.html.
