  Synthesis of 2.beta.-Acyl-3.beta.-aryl-8-azabicyclo[3.2.1]octanes and Their Binding Affinities at Dopamine and Serotonin Transport Sites in Rat Striatum and Frontal Cortex

  摘要：

  A novel entry to tropane analogs of cocaine was developed on the basis of the reaction of rhodium-stabilized vinylcarbenoids with pyrroles. These analogs were tested:in binding to dopamine and serotonin (5-HT) transporters in:membranes from rat striatum and frontal cortex. In all the analogs, the aryl group at the 3-position was directly bound to the tropane ring (as in WIN-35,428), and methyl or ethyl ketone moieties were present at the a-position instead of the typical ester group. The series of analogs containing a 2-naphthyl group at the 3-position were most potent, with K-i values < 1 nM in binding to both dopamine and 5-HT transporters. Although the unsubstituted 2-naphthyl analog was nonselective at dopamine and 5-HT transport sites, other compounds:were selective for either site. In general, compounds with relatively small substituents on the aromatic moiety (such as p-methyl or p-fluoro) were relatively selective for the dopamine transporters, while a p-isopropylphenyl derivative was selective:for the 5-HT transport sites. This latter compound represents the first N-methyltropane derivative specific for 5-HT transporters. Resolution of two of the most significant analogs was achieved by HPLC on a chiral stationary phase; the active enantiomer of a 2-naphthyl analog exhibited K-i values of <0.1 nM at both dopamine and 5-HT transporter sites.

  Using cinchona alkaloid-derived primary amines as catalysts and aqueous hydrogen peroxide as the oxidant, we have developed highly enantioselective Weitz-Scheffer-type epoxidation and hydroperoxidation reactions of α,β-unsaturated carbonyl compounds (up to 99.5:0.5 er). In this article, we present our full studies on this family of reactions, employing acyclic enones, 5-15-membered cyclic enones, and

  A rhodium-catalyzed intermolecular hydroacylation reaction of vinyl cyclobutanols with non-chelating aldehydes has been developed. This reaction offers a new and atom-economical approach for the selective preparation of 1,5-diketones in high yields. Experimental data suggest a sequential ring-opening, transfer hydrogenation, and hydroacylation mechanism. We propose that aldehyde decarbonylation is

  日期：1968.6

  oxidation of t-alcohols in water - dioxane - sodium hydroxide system has been examined. The possibility of production of t-alkoxy radicals by anodic oxidation of t-alcohols in the electrolytic system was found. The relative ease of bond scission of the intermediate t-alkoxy radical was determined by quantitative analysis of the mixture of ketones produced. The relative rates of cleavage decrease in the order:
