  dium联吡啶催化的中环氧化物对映选择性氨解。

  摘要：

  optimized联吡啶催化苯胺和O-烷基羟胺对映体环氧化物的对映选择性加成已得到优化，并扩展到广泛的环氧化物和胺中。芳族内消旋环氧化物通常以优异的对映选择性提供相应的1,2-氨基醇，而脂族内消旋环氧化物仅在氨解反应中产生中等对映选择性。催化剂的加入量可以降低到仅5mol％，而对收率和对映选择性只有很小的影响。已经观察到强烈的正非线性效应，指出了催化剂的聚集现象。

  equivalents in a formal vinylidene insertion process, providing the first general synthetic route to enantioenriched alkylidenecyclobutanones. The addition of an alkenyl-Grignard reagent leads to an alkenylcyclopropanol capable of electrophilic activation by N-bromosuccinimide, triggering a regio- and stereospecific 1,2-migration and affording alkylidenecyclobutanones after elimination. Activation of the

  active catalytic system for the carbonylation of meso- and terminal epoxides to β-lactones is described. The active catalyst, analogous to Coates’ catalyst, is generated in situ from commercially available (TPP)CrCl and Co2(CO)8. This practical system circumvents the preparation of air sensitive cobaltate salts, operates at low catalyst loadings, and allows the carbonylation of functionalized, sterically

  The isolation and structure determination of the naturally occurring LTB4 receptor antagonist Leucettamine A (1) was recently reported.1 Herein we describe the synthesis of this natural product, the preparation of several analogues, and their effectiveness as antagonists of [H-3]LTB4 binding to intact human U-937 cells. Total synthesis of Leucettamine A 1) is achieved by a convergent route which takes advantage of the elements of symmetry within the molecule. Syntheses of analogues of 1, which lacked the same degree of symmetry, are achieved by a different approach starting from alpha-amino acids. The natural product 1 inhibits [H-3]LTB4 binding to its receptors on intact human U-937 cells with a K(i) = 3.5 +/- 0. 8 muM and is devoid of measurable agonist activity at the concentrations tested. 2-Amino imidazole analogues of 1 lacking the dioxolane groups were prepared. Generally these are significantly less potent than 1. However, one (26), designed on the basis of a putative structural overlay with LTB4, demonstrated potency comparable to that of the natural product (K(i) = 2.4 +/- 0.2 muM).
