Takasago SEGPHOS 配体及钌类催化剂在不对称氢化反应中的应用

百灵威科技有限公司2013年4月16日 10:37 点击:1142

SEGPHOS®是继BINAP之后发现的一种应用于不对称反应中的手性配体,它的芳香环之间具有较狭窄的二面角,因此SEGPHOS®能增加金属配合物的对映选择性与活性。百灵威提供STREM品牌SEGPHOS®不用本金就能赚钱的方法配体及钌催化剂,适用底物广、催化活性高(TOF可达30,000以上,用量少、成本低)、对映选择性好(ee>95%,纯化更简单)、收率高(可达99%),供货稳定,可有效帮助您加快科研进程。

SEGPHOS® 配体

Technical Notes:
1. Iridium-catalyzed asymmetric hydrogenation of quinolines activated by chloroformates.
2. Diastereo- and enantioselective ruthenium-catalyzed hydrohydroxyalkylation of 2-silyl-butadienes.
3. Asymmetric Ag-catalyzed cycloadditions.

SEGPHOS® 钌类催化剂

Technical Notes:
1. Highly active highly enantioselective catalyst for hydrogenation of functionalized ketones. Slightly higher temperature is necessary to activate the cymene complexes. Asymmetric hydrogenation of α-substituted-β-alkyl-β-ketoesters accompanied by dynamic kinetic resolution.
2. Highly enantioselective, highly active catalyst for hydrogenation of functionalized ketones. The chlororuthenate salts show catalytic activity at relatively low temperature.
3. Biaryl bisphosphine ligand with narrow dihedral angle. The DM-SEGPHOS ligand, as the ruthenium complex, gives superior enantioselectivity and diastereoselectivity in the asymmetric hydrogenation of α-substituted-β-ketoesters. Ruthenium catalyzed enantioselective synthesis of β amino acids by hydrogenation.
