On December 17, 2020, Wang, Chen; Liang, Haijing; Hang, Zhaojun; Wang, Zhao-yan; Xie, Qinjian; Xue, Weihua published an article.Product Details of 2873-29-2 The title of the article was Lewis acid/base pair as a catalytic system for α-stereoselective synthesis of 2-deoxyglycosides through the addition of alcohols to glycals. And the article contained the following:
This report describes the α-stereoselective addition of alcs. to glycals promoted by a cooperative Lewis acid/base pair catalytic system composed of B(C6F5)3 and tetrabutylammonium bromide (TBAB), which provides access to 2-deoxylglycosides in high yields. A mechanistic investigation supported by NMR anal. highlights the possible involvement of nucleophilic addition through boron-induced activation of alcs. under the assistance of TBAB. The protocol discussed here features the high stereoselectivity, mild reaction conditions, inexpensive and stable catalysts, and a broad substrate scopes. The experimental process involved the reaction of (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate(cas: 2873-29-2).Product Details of 2873-29-2
