The unique advantages conferred by incorporation of all-substituted carbon stereocenters in organic mols. have gained widespread recognition. In this work, we describe a three-component cyclization to access C-2 fluoroalkylated oxazolidines by fragments assembly of readily available silyl enol ether, fluoroalkyl halide, and chiral amino alc. in a single reaction vessel, which provides an efficient strategy for expanding the pool of pharmaceutically important heterocycles featuring an all-substituted carbon stereocenter. This process proceeds efficiently in a chemo-, regio-, and stereoselective fashion under mild reaction conditions at room temperature and exhibits broad functional group tolerance. The successful realization of this controlled heteroannulation sequence relies on distinctive perfluoroalkylation, regio- and stereoselective radical cyclization through visible-light photoredox catalysis. Moreover, a one-pot procedure directly employing ketone as substrate has also been achieved.

(1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol(cas: 126456-43-7) belongs to anime. The methylamines occur in small amounts in some plants. Many polyfunctional amines (i.e., those having other functional groups in the molecule) occur as alkaloids in plants—for example, mescaline, 2-(3,4,5-trimethoxyphenyl)ethylamine; the cyclic amines nicotine, atropine, morphine, and cocaine; and the quaternary salt choline, N-(2-hydroxyethyl)trimethylammonium chloride, which is present in nerve synapses and in plant and animal cells.Category: alcohols-buliding-blocks
