The American Mercury, 5 October 1813 (vol. 30, no. 1527) - Newspaper

Volumes of interest were published between 1812 and 1815 with articles about the War of 1812. Issue for Oct. 5, 1813 includes: A report announces the arrival of Commodore Rodgers in the U.S. frigate President, in the harbor from his "brilliant cruise" of five months. There is also a list of the captures Rodgers made during his cruise. The feature item in this issue, however, is the famous dispatch sent by Oliver Hazard Perry at the Battle of Lake Erie to General William Henry Harrison. The dispatch, taken from the Chillicothe Supporter, of Sept. 15, is datelined "U.S. Brig Niagara, off the Western Sister, head of Lake Erie, September 10th, 1813, 4 P.M.", and reads: "Dear General, we have met the enemy; and they are ours! Two ships, two brigs, one schooner and one sloop. Yours with great respect and esteem." The dispatch is signed in type: O. H. Perry.

Model studies toward the total synthesis of thebaine by an intramolecular cycloaddition strategy

The present studies describe recent progress toward the synthesis of the thebaine. Model substrates were synthesized using pyridazine derivatives as a starting material, which allowed to assess the key Diels-Alder reaction as a route to construct the thebaine core.

The Use of Ipso-dihydrodiols Enzymatically Derived from Benzoic Acid in Enantioselective Synthesis. Appoaches to Total Synthesis of Vinca Alkaloids

The present studies describe our recent progress in target oriented synthesis of complex organic molecules from aromatic precursors. The latest synthetic approaches toward vinca alkaloids are described and include the construction of model substrates for the investigation into Diels-Alder, radical cascade, and tandem Michael addition reactions as possible routes to the family of alkaloids. Also described are the chemoenzymatic syntheses of the natural product (-)-idesolide and unnatural polyhydroxylated pyrrolidines generated from the biotransformation of benzoic acid with Ralstonia eutropha B9.

Racemic and Enantioselective Total Syntheses of Mosquito Oviposition Pheromone from a Naturally Available Unsaturated Fatty Acid

The unnatural threo-6-acetoxy-5-hexadecanolide and the natural mosquito oviposition pheromone erythro-6-acetoxy-5-hexadecanolide were synthesized in a diastereodivergent fashion in 44% and 33% overall yield respectively from 5-bromovaleric acid and undecanal. The key step utilized a chemoenzymatic epoxidation-lactonization of a naturally available fatty acid to form the 6-hydroxy-5-hexadecanolide core.17 The epoxidation strategy was later adapted to allow for an asymmetric synthesis. Shi epoxidation afforded highly enantioenriched (5R, 6R)-6-hydroxyhexadecanolide (er = 10) in 70 % overall yield. Other derivatives of the chiral ketone catalyst were also screened. Finally, attempts were made to obtain the correct stereochemistry at C(6) of the target with a dynamic kinetic transformation using lipase and a transfer hydrogenation catalyst. Epimerization of the lactol with the transfer hydrogenation catalyst was successful, but lipase mediated reactions halted at <10 % conversion.

Chemoenzymatic Total Synthesis of Morphine alkaloids: Synthesis of Dihydrocodeine and Hydrocodone via a Double Claisen Strategy and ent-Hydromorphone via an Oxidative Dearomatization/intramolecular [4+2] Cycloaddition

This thesis describes the chemoenzymatic synthesis of three morphine alkaloids. The total synthesis of dihydrocodeine and hydrocodone was accomplished starting from bromobenzene in 16 and 17 steps, respectively. The key steps included a microbial oxidation of bromobenzene by E. coli JM109 (pDTG601A), a Kazmaier-Claisen rearrangement of glycinate ester to generate C-9 and C-14 stereo centers, a Johnson-Claisen rearrangement to set the C-13 quaternary center, and a C-10/C-11 ring closure via a Friedel-Crafts reaction. In addition, the total synthesis of ent-hydromorphone starting from β-bromoethylbenzene in 12 steps is also described. The key reactions included the enzymatic dihydroxylation of β-bromoethylbenzene to the corresponding cis-cyclohexadienediol, a Mitsunobu reaction, and an oxidative dearomatization followed by an intramolecular [4+2] cycloaddition.
