Uozumi, Yasuhiro published the artcile(R)-2-diphenylphosphino-2′-methoxy-1,1′-binaphthyl, Quality Control of 126613-06-7, the publication is Organic Syntheses (2002), 1-13, database is CAplus.
The preparation of title compound is described in details, starting from (R)-(+)-1,1′-bi-2-naphthol. (R)-1,1′-binaphthalene-2,2′-ditriflate was coupled with diphenylphosphine oxide under Pd(OAc)2-dppb catalysis affording (R)-2-diphenylphosphinyl-2′-trfluoromethanesulfonyloxy-1,1′-binaphthalene, then after hydrolysis the MeI etherification gave (R)-2-diphenylphosphinyl-2′-methoxy-1,1′-binaphthalene, which was reduced to the title compound by HSiCl3.
Organic Syntheses published new progress about 126613-06-7. 126613-06-7 belongs to esters-buliding-blocks, auxiliary class Chiral Diphenols, name is (R)-[1,1′-Binaphthalene]-2,2′-diyl bis(trifluoromethanesulfonate), and the molecular formula is C12H14BNO2, Quality Control of 126613-06-7.
