A practical and scalable synthesis of in vivo sphingosine-1-phosphate lyase inhibitor LX2931 (1) is described. The synthetic route features an improved Büchi cyclocondensation of 2-ethoxyacrylonitrile (3) with either 1-amino-1-deoxy-d-fructose acetate (4a) or d-(+)-glucosamine hydrochloride (4b) to produce 1-(4-((1R,2S,3R)-1,2,3,4-tetrahydroxybutyl)-1H-imidazol-2-yl)ethanone (2, THI), followed by oximation
Abstract Reactions of 2-amino-2-deoxy- d -glucose and its N -butyl derivative with 1-ethoxy-2-nitroethene produced 2-deoxy-2-[(2-nitrovinyl)amino]- d -glucose ( 6 ) and its N -butyl derivative ( 8 ), respectively, in high yields. The spectra of these compounds indicated that they were α,β-anomeric mixtures, and also that 6 existed as equilibrium mixtures of the Z - and E -geometrical isomers, the proportions
