  The synthesis is based upon (1) the use of 3-p-toluenesulfonyl-sn-glycerol to provide the stereocenter for construction of the optically active lysophospholipid molecule, (2) tetrahydropyranylation of the secondary alcohol function to achieve orthogonal protection of the sn-2- and sn-3-glycerol positions, and (3) elaboration of the phosphodiester headgroup using a 2-chloro-1,3,2-dioxaphospholane/trimethylamine

  报道了溶血磷脂酰胆碱的新的立体选择性合成。合成是基于（1）利用3- p -toluenesulfonyl- SN -甘油一种用于施工光学活性溶血磷脂分子的提供立构，（2）二级醇官能的tetrahydropyranylation来实现的正交保护SN - 2-和sn -3-甘油位置，以及（3）使用2-氯-1,3,2-二氧杂膦环/三甲胺序列精制磷酸二酯头基。在进行合成的过程中，发现sn -3- p的甲氧基乙酸酯置换-甲苯磺酸酯产生反应性甲氧基乙酰基酯，其随后可以用甲醇/叔丁胺选择性地裂解，而在sn -1位的酯基保持不受影响。已显示该序列适合于制备经光谱标记的溶血磷脂酰胆碱。这些化合物之一很容易转化为双标记的混合链磷脂酰胆碱，可用于脂解酶的实时荧光共振能量转移（FRET）分析。此外，这项工作还导致了新的合成策略，该策略基于在存在其他碱不稳定基团（例如FMOC衍生物）的情况下对甲苯磺酰基的化学选择性

  The present invention aims to provide a polymerizable compound that has high storage stability without causing crystal precipitation when added to a polymerizable composition and to provide a polymerizable composition containing the polymerizable compound. A polymer film produced by polymerization of the polymerizable composition has a low haze, high thickness uniformity, low occurrence of nonuniform orientation, high surface hardness, high adhesiveness, and good appearances and fewer orientation defects even after ultraviolet irradiation. The present invention also aims to provide a polymer produced by polymerization of the polymerizable composition and an optically anisotropic body produced from the polymer.

• Multidentate ¹⁸F-Polypegylated Styrylpyridines As Imaging Agents for Aβ Plaques in Cerebral Amyloid Angiopathy (CAA)

  beta-Amyloid plaques (A beta plaques) in the brain are associated with cerebral amyloid angiopathy (CAA). Imaging agents that could target the A beta plaques in the living human brain would be potentially valuable as biomarkers in patients with CAA. A new series of F-18 styrylpyridine derivatives with high molecular weights for selectively targeting A beta plaques in the blood vessels of the brain but excluded from the brain parenchyma is reported. The styrylpyridine derivatives, 8a-c, display high binding affinities and specificity to A beta plaques (K-i = 2.87, 3.24, and 7.71 nM, respectively). In vitro autoradiography of [F-18]8a shows labeling of beta-amyloid plaques associated with blood vessel walls in human brain sections of subjects with CAA and also in the tissue of AD brain sections. The results suggest that [F-18]8a may be a useful PET imaging agent for selectively detecting A beta plaques associated with cerebral vessels in the living human brain.

  [18F]-Fluoromisonidazole is the most widely used radiopharmaceutical for imaging hypoxia in tumors. The precursor for [18F]-fluoromisonidazole was prepared from 1,3-dibromo-2-propanol in 5 steps from available materials and straightforward purification steps. The overall yield for this synthesis was 18%. Copyright © 2005 John Wiley & Sons, Ltd.
