  serve as an efficient catalyst for hydrophosphonylation of aldehydes and aldimines, giving the corresponding alpha-hydroxy and alpha-amino phosphonates with high enantioselectivity, respectively. The scope of the hydrophosphonylation was wide, and both aliphatic and aromatic aldehydes and aldimines were successfully used as substrates for the reaction. The potent catalysis of the complex is attributed to

  以模块化合成方式新合成了光学活性铝（salalen）配合物2，发现它可作为醛和醛亚胺氢膦酰化的有效催化剂，分别得到相应的具有高对映选择性的α-羟基和α-氨基膦酸酯. 氢膦酰化的范围很广，脂肪族和芳香族醛和醛亚胺都成功地用作反应的底物。该复合物的强大催化作用归因于其独特的结构：它采用扭曲的三角双锥体构型，这使得 salalen 配体呈顺式-β 样结构，其中手性氨基位于靠近金属中心的位置。

  Rh-catalyzed asymmetric hydrogenation of challenging α-keto phosphonates has been developed. With a new chiral phosphine–phosphoramidite ligand, a wide range of α-keto phosphonates were hydrogenated to afford the corresponding (R)-α-hydroxy phosphonates with moderate to good enantioselectivities (up to 87% ee).

  A process for producing an asymmetric compound using a metal complex containing no rare earth metal element is disclosed. The process affords an optically active compound having high optical purity. Optically active binaphthol having the chemical formula ##STR1## and lithium aluminum hydride are reacted, or the optically active binaphthol, a dialkyl aluminum hydride, and a base containing an alkali metal (or a base containing alkaline earth metal) are reacted to prepare a metal complex comprising optically active binaphthol, aluminum, and alkali metal (or alkaline earth metal). This metal complex can be used as a catalyst to perform an asymmetric Michael reaction, an asymmetric phosphonylation reaction, or the like, to obtain, in a high yield, an asymmetric compound having high optical purity.
