以光学纯的S-2,2’-螺二氢茚-1,1’-二酮为原料,合成了新型螺环氧膦配体(1R,2s,1's)-1,1'-双(二苯基膦氧)-2,2’-螺二氢茚烷(s-cis,trans-SpiroBIP),考查了催化剂[Rh(COD)(R-cis,cis—SpiroBIP)]BF4,[Rh(COD)(s-cis,trans-SpiroBIP)]BR和Ir(R-cis,cis-SpiroBIP)(COD)C1在不对称催化氢化反应中的应用。
A novel chiral bisphosphinite ligand S-cis, trans-SpiroBIP was synthesized. The applications of catalysts, [ Rh (COD) ( R-cis, cis-SpiroBIP) ] BF4, [ Rh (COD) ( S-cis, trans-SpiroBIP) ] BF4 and Ir(R-cis, cis-SpiroBIP)(COD) C1 were researched in catalytic asymmetric hydrogenation.
