  Precise control of the formation of a covalent and an ionic bond in carbocation-carbanion combination reactions

  摘要：

  The electronic effect on the selectivity of covalent or ionic bond formation was examined for the reaction of Kuhn's anion 1- (C67H39-; tris(7H-dibenzo[c,g]fluorenylidenemethyl)methide ion) and 1-aryl-2,3-dicyclopropylcyclopropenylium ions. The carbocation stability was progressively changed by varying the substituent on the phenyl ring, while the steric effect was kept essentially unchanged. The cations having the p-chlorophenyl (2a+), phenyl (2b+), m-methylphenyl (2c+), or m,m'-dimethylphenyl (2d+) group gave a covalent product, whereas a carbocation-carbanion salt was obtained from the cations having the p-methylphenyl (2e+) or p-methoxyphenyl (2f+) group. The reduction potentials E(red) of the cations, as determined by cyclic voltammetry, showed that the formation of the covalent or ionic product is switched by a small difference in stability (less-than-or-equal-to 0.4 kcal/mol) between 2d+ and 2e+. In chloroform, the salts 1-2e+ and 1-2f+ were transformed into covalent forms 1-2e and 1-2f, which can exist only in solution. When 1-(2a-d) and 1-2e,f+ were dissolved in DMSO, equilibrium between a covalent compound and ions was established. A plot of the free energy of heterolysis DELTAG(het)-degrees for 1-(2a-f) against the E(red) of the corresponding cations 2a-f+ showed that DELTAG(het)-degrees decreases as the cation is more stabilized. The heterolysis in DMSO was shown to be enhanced by ca. 13 kcal/mol both by the steric congestion in the covalent molecules and the stabilization of the cyclopropenylium ions by solvation.

  A catalytic asymmetric intramolecular homologation of simple ketones with α‐diazoesters was firstly accomplished with a chiral N,N′‐dioxide–Sc(OTf)3 complex. This method provides an efficient access to chiral cyclic α‐aryl/alkyl β‐ketoesters containing an all‐carbon quaternary stereocenter. Under mild conditions, a variety of aryl‐ and alkyl‐substituted ketone groups reacted with α‐diazoester groups

  首先用手性N，N'-二氧化物-Sc（OTf）3配合物完成了简单的酮与α-重氮化合物的催化不对称分子内同源性。这种方法可以有效地获得含有全碳季立体中心的手性环状α-芳基/烷基β-酮酸酯。在温和的条件下，各种芳基和烷基取代的酮基通过分子内加成/重排过程与α-重氮酸酯基团平稳反应，从而以高收率和对映体过量生成β-酮酸酯。

• Substituted Indole-5-carboxamides and -acetamides as Potent Nonpeptide GnRH Receptor Antagonists

  The 2-aryltryptamine class of GnRH receptor antagonists has been modified to incorporate carboxamide and acetamide substituents at the indole 5-position. With either a phenol or methanesulfonamide terminus on the N-aralkyl side chain, potent binding affinity to the GnRH receptor was achieved. A functional assay for GnRH antagonism was even more sensitive to structural modification and revealed a strong preference for branched tertiary amides. (C) 2001 Elsevier Science Ltd.
