Author is Cianferotti, Claudio; Barreca, Giuseppe; Bollabathini, Venkatesh; Carcone, Luca; Grainger, Damian; Staniland, Samantha; Taddei, Maurizio.
We report here a short enantioselective synthesis of Ozanimod (I), a potent modulator of the enzyme Sphingosine-1-phosphate receptor (S1PR), recently approved by FDA and EMA for the treatment of relapsing-remitting multiple sclerosis. Amongst different synthetic approaches explored, we achieved the best result introducing the stereogenic center in the last step through imine asym. transfer hydrogenation (ATH) using Wills’ catalysts. Besides the reduced numbers of enantiomeric purity controls required, this process culminates in an exceptionally high enantioselective reductive amination obtained with com. available tethered Ru catalysts. Starting from com. available 4-cyano-indanone, enantiomerically pure Ozanimod was obtained in 5 steps in 62% overall yield and 99% ee.
As far as I know, this compound(17739-45-6)HPLC of Formula: 17739-45-6 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
