2-Pyridonate Titanium Complexes for Chemoselectivity. Accessing Intramolecular Hydroaminoalkylation over Hydroamination
作者:Eugene Chong、Laurel L. Schafer
DOI:10.1021/ol402890m
日期:2013.12.6
Chemoselectivity of intramolecularhydroaminoalkylation over hydroamination has been achieved with a bis(3-phenyl-2-pyridonate) titanium complex. Primary aminoalkenes are selectively α-alkylated by C–H functionalization adjacent to nitrogen to access five- and six-membered cycloalkylamines with a good substrate-dependent diastereoselectivity of up to 19:1.

日期:2007.7
diastereo- and enantioselective syntheses of trans-cycloalkyl amines was accomplished through a three-step sequence consisting of: (1) asymmetric transfer hydrogenation through dynamickineticresolution of bicyclic and monocyclic α-substituted ketones using HCO2H/Et3N as the hydrogen source and TsDPEN-based Ru(II) catalysts, (2) nucleophilic hydroxyl to azide substitution of the resulting cis-cycloalkanols
通过三个步骤完成反式环烷基胺的非对映和对映选择性合成:(1)通过动态动力学拆分HCO 2 H / Et 3 N作为双环和单环α-取代的酮进行不对称转移氢化。氢源和基于TsDPEN -钌(II)催化剂,(2)的亲核的羟基向所得的叠氮取代的顺式改性Mitsunobu条件下使用-cycloalkanols二苯基磷叠氮化物,和(3)还原的反式-叠氮化物中间体与的LiAlH 4的PPh 3 / H 2 O达到所需目标。
