Catalytic stereoconvergent synthesis of homochiral ▫$\beta-CF_3$▫, ▫$\beta-SCF_3$▫, and ▫$\beta-OCF_3$▫ benzylic alcoholsCotman, Andrej Emanuel ...We describe an efficient catalytic strategy for enantio- and diastereoselective synthesis of homochiral β-CF3, β-SCF3, and β-OCF3 benzylic alcohols. The approach is based on dynamic kinetic ... resolution (DKR) with Noyori–Ikariya asymmetric transfer hydrogenation leading to simultaneous construction of two contiguous stereogenic centers with up to 99.9% ee, up to 99.9:0.1 dr, and up to 99% isolated yield. The origin of the stereoselectivity and racemization mechanism of DKR is rationalized by density functional theory calculations. Applicability of the previously inaccessible chiral fluorinated alcohols obtained by this method in two directions is further demonstrated: As building blocks for pharmaceuticals, illustrated by the synthesis of heat shock protein 90 inhibitor with in vitro anticancer activity, and in particular, needle-shaped crystals of representative stereopure products that exhibit either elastic or plastic flexibility, which opens the door to functional materials based on mechanically responsive chiral molecular crystals.Source: ACS Organic & Inorganic Au. - ISSN 2694-247X (Vol. 2, iss. 5, 2022, str. 396-404)Type of material - e-article ; adult, seriousPublish date - 2022Language - englishCOBISS.SI-ID - 111499267
