1′-binaphthyl-2,2′-diamine with trigol bis aldehyde were prepared and characterized by microanalysis, 1H NMR, UV/Vis. spectroscopy, optical rotation and mass spectroscopy. Highlyenantioselective nitroaldol reaction of various aromatic and aliphatic aldehydes with nitromethane in presence of several bases were carried out in the presence of in situ generated Cu(I)/Cu(II) complexes with chiral macrocyclic
衍生自1 R,2 R -(-)-1,2-二氨基环己烷,1 R,2 R -(+)-1,2-二苯基-1,2-二氨基乙烷的手性大环Salen配体1'-3' [R )- (+) - 1,1 '联萘-2,2 ' -二胺与trigol二醛制备和表征通过元素分析,1 H NMR,UV /可见光。光谱学,旋光性和质谱学。在具有几种碱的情况下,在具有手性大环赛伦配体1'–3'的原位生成的Cu(I)/ Cu(II)配合物的存在下,进行了各种芳香族和脂肪族醛与硝基甲烷的高度对映选择性硝基醛反应在RT。如果在3-甲基苯甲醛和4-硝基苯甲醛的条件下,大约有对映选择性(ee,〜95%)的β-硝基醇具有很高的收率(相对于醛而言高达92%)。在2,6-二甲基吡啶为碱的情况下,使用具有CuCl 2 ·2H 2 O的手性大环赛伦配体3'进行30小时的反应。手性大环赛伦催化剂3介导的硝基羟醛工艺是可回收的(最多8个循环,其性能
