synthesized from natural amino alcohols or by reduction of formyl esters of α-amino acids and PPh2Cl. Their cationic rhodium complexes have been found to be excellent catalysts for enantioselective hydrogenation of dehydroamino acids (ee ∼ 86%, yield ∼ 100%) for example. Asymmetric reduction of ketones can also be performed with the new alkyl AMPP* modified rhodium catalyst (ee 50%).
由天然氨基醇或通过还原α-氨基酸和PPh 2 Cl的甲酸酯直接合成手性氨基膦次膦酸酯配体(AMPP)。已经发现它们的阳离子铑配合物是脱氢氨基酸的对映选择性加氢的优良催化剂(ee〜86%,收率〜100%)。酮的不对称还原也可以用新型烷基AMPP *改性铑催化剂(ee 50%)进行。
