Regioselective Reduction of NAD+ Models with [Cp*Rh(bpy)H]+: Structure-Activity Relationships and Mechanistic Aspects in the Formation of the 1,4-NADH Derivatives
作者:H. Christine Lo、Olivier Buriez、John B. Kerr、Richard H. Fish
The hydride transfer mechanism of the NAD+ model compound 1 to its 1,4-NADH derivative 3 [Eq. (1)] is proposed to be a consequence of the critical role of the carbonyl group of the amide to coordinate to the ring-slipped η5 - to η3 -Cp*Rh metal center of the catalyst [Cp*Rh(bpy)H]+ , prepared in situ from 2, while a steric effect of a substituent in the 3 position, for example, C(O)NEt2 , was found
NAD +模型化合物1向其1,4-NADH衍生物3的氢化物转移机理[等式。(1)]建议成为的酰胺的羰基中的关键作用的结果,以协调环滑动η 5 -至η 3催化剂的-Cp *铑金属中心的[Cp *的Rh(联吡啶)由2原位制备的H] +,同时发现3位上的取代基(例如C(O)NEt 2)的空间效应完全抑制了这种区域选择性还原。bpy = 2,2'-联吡啶,Cp * = C 5 Me 5,OTf =三氟甲磺酸根。
