AbstractEmergency physicians constantly have multiple ethical obligations in the emergency department. They must understand these sometimes conflicting obligations and learn to prioritize. A case discussion is presented that exemplifies the conflict between patient privacy and society's right to know. Specific aspects of HIV testing and obtaining patient consent are presented. Teaching physicians are encouraged to use such common cases for “ethics case discussion.”

Bisoxazoline and Bioxazoline Chiral Ligands Bearing 4-Diphenylmethyl Shielding Substituents. Diels-Alder Reaction of Cyclopentadiene with 3-Acryloyl-2-oxazolidinone Catalyzed by the Aqua Nickel(II) Complex
4′-bis(diphenylmethyl)-2,2′-bioxazoline and 2,2′-isopropylidenebis(4-diphenylmethyloxazoline), and further to complexes with copper(II) trifluoromethanesulfonate and nickel(II) perchlorate hexahydrate. The nickel(II) aqua complex derived from the bisoxazoline effectively catalyzes the Diels-Alderreactions of cyclopentadiene with 3-acryloyl-2-oxazolidinone in high endo-selectivities and moderate enantioselectivities
Enantiopure 2-amino-3,3-diphenyl-1-propanol 已通过hidantoin 路线从二苯乙醛开始合成,然后通过手性 HPLC 进行后续的官能团转化和光学拆分。这种氨基醇可以转化为两个新的手性配体:4,4'-双(二苯基甲基)-2,2'-生物恶唑啉和 2,2'-异亚丙基双(4-二苯基甲基恶唑啉),并进一步与铜(II)复合三氟甲磺酸盐和高氯酸镍 (II) 六水合物。衍生自双恶唑啉的镍 (II) 水络合物通过方形平面过渡结构有效催化环戊二烯与 3-丙烯酰基-2-恶唑烷酮的狄尔斯-阿尔德反应,具有高内向选择性和中等对映选择性。
