标题:对映选择性铑催化的原子经济宏观内酯化
摘要:描述了形成大内酯的高度吸引人的途径,大内酯形成多种多样的天然化合物的环状支架.尽管已经探索了许多针对该结构基序的化学方法,但是环化的不对称变体是前所未有的.在这里,我们通过ω-烯基取代的羧酸的分子内原子-经济铑催化的偶合来呈现对映选择性大内酯化作用.使用改良的二重配体,手性dtbm二联体,可实现高对映选择性(高达93% Ee).该反应可耐受多种功能,包括α,β-不饱和羧酸和二肽,并提供所需的具有高对映体和非对映体选择性的大环.

摘要:The present invention has as its object to provide an iridium complex represented by the general formula:n n[(I r H L 1 L 2 ) 2 (μ−X 1 )(μ−X 2 )(μ−X 3 )]X 4   (1)n n(wherein L 1 and L 2 may be the same or different and each represent a monodendate neutral ligand, or each cooperate with the other to form a bidendate neutral ligand; X 1 , X 2 and X 3 may be the same or different, and each represent a halogen atom; and X 4 is a counter-anion). Also, the present invention provides a novel catalyst which can achieve excellent performance as a catalyst for asymmetric synthesis, especially asymmetric hydrogenation, in terms of chemical selectivity, enantioselectivity and catalytic activity, and the like.
