A highly regio‐ and enantioselective rhodium‐catalyzed 1,4‐addition of arylboronic acids to β,γ‐unsaturated α‐ketoamides using a simple new chiral sulfinylphosphine ligand is described. This transformation provides an attractive approach to construct chiral nonracemic γ,γ‐diarylsubstituted carbonyl compounds, as exemplified in the concise syntheses of sertraline and tetrahydroquinoline‐2‐carboxylamide
本文描述了使用简单的新手性亚磺酰基膦配体将高区域和对映体选择性的铑催化的1,4-芳基硼酸加成到β,γ-不饱和α-酮酰胺上的方法。这种转化为构建手性非外消旋的γ,γ-二芳基取代的羰基化合物提供了一种有吸引力的方法,如舍曲林和四氢喹啉-2-羧酰胺的简明合成中所举例说明的那样。
