The present invention relates to a ruthenium carbonyl complex that is represented by the following Formula (1):
RuXY(CO)(L) (1)
(in the Formula (1), X and Y, which may be the same or different from each other, represent an anionic ligand and L represents a tridentate aminodiphosphine ligand which has two phosphino groups and a —NH— group), its production method, and a method for production of alcohols by hydrogenation-reduction of ketones, esters, and lactones using the complex as a catalyst.
The ruthenium carbonyl complex of the invention has a high catalytic activity and it can be easily prepared and handled.
Stereoselective total synthesis of lysocellin, the representative polyether antibiotic of the lysocellin family. Part 1. Synthesis of C1–C9 and C16–C23 subunits
The C1–C9 (4) and C16–C23 subunits (9) of lysocellin (1), a representative polyetherantibiotic, were synthesized stereoselectively from D-glucose and D-mannitol. Stereocontrolled hydroboration, Michael reaction, Grignard reaction, etc. were successfully applied.
