  Synthesis of Some Bridgehead-Bridgehead-Disubstituted Bicyclo[1.1.1]pentanes

  摘要：

  The synthesis of a wide variety of 1,3-disubstituted bicyclo[1.1.1]pentanes is described, with particular emphasis on the generation of a series of S-X-substituted bicyclo[1.1.1]pentyl bromides required for solvolytic studies. Functional group manipulation at the bridgehead was readily accomplished in the majority of cases by radical processes in some instances, transformations were effected via carbanionic-type intermediates.

  of inflammatory and pain processes. The synthesis and structure-activity relationship studies encompassing the isothiocyanate pharmacophore have produced potent low nanomolar inhibitors for hNAAA, while exhibiting high selectivity (>100-fold) against other serine hydrolases and cysteine peptidases. We have followed a target-based structure–activity relationship approach, supported by computational methods

• Bridgehead Carbocations: A Solvolytic Study of 1-Bromobicyclo[1.1.1]pentane and Its Bridgehead-Substituted Derivatives

  The rate constants (k) for solvolysis of a range of 3-X-substituted bicyclo[1.1.1]pentyl bromides in 80% aqueous ethanol have been measured and a linear relationship found to exist between log k and the inductive/field constant sigma(I). These observations, together with the results of isotope and solvent effect studies described below, have been interpreted as evidence for the formation of 1-bicyclo[1.1.1]pentyl cations in the ionization step in preference to mechanisms in which either ring-opening is concerted with ionization to give 3-methylenecyclobutyl cations or ionization is accompanied by ring-contraction to give bicyclo[1.1.0]butyl-1-carbinyl cations. The latter mechanisms would have been expected to show the effects of strong pi-donor substituent participation, a phenomenon which was not observed. A comparison of the rates of solvolysis of the parent bromide and its 3-deuterated analog is characterized by a large deuterium-isotope effect (k(H)/k(D) = 1.30) which, combined with the observation that 1-bromobicyclo[1.1.1]pentane solvolyses with enhanced rates in solvents which are strong hydrogen bonding accepters, lends support to the view that the 1-bicyclo[1.1.1]pentyl cation derives substantial stabilization from sigma-hyperconjugative interactions.
