Reactions of certain purin-8-ols with phosphorus oxychloride in the presence of N,N-diethylaniline

Creator:: Ladwig, Laurence Gene
Abstract:: The reaction of certain purin-8-ols with phosphorus oxychloride and N,N-diethylaniline are described. 9-Amino-6-chloropurin-8-ol monohydrate reacted with phosphorus oxychloride and N, N-diethylaniline to yield the phosphorus oxychloride adduct. Other purin-8-ols were prepared and the production of analogs similar to the previously mentioned adduct was attempted. 6-Chloropurin-8-ol and 6, 9-diaminopurin-8-ol hydrochloride monohydrate...

The synthesis of substituted 1, 8-naphthyridines by the Doebner reaction

Creator:: Samalapa, Prasit
Abstract:: The possibility of synthesizing 1, 8-naphthyridines by the Doebner reaction has appeared in many reports. The method involves the introduction of electron releasing groups in the 6-position of 2-amino pyridine to activate the C-3 position. Previously Lewis used 6-methyl-2-amino pyridine with benzaldehyde and pyruvic acid, in an attempt to prepare...

The siloxy-cope rearrangement of 1,2-divinyl-1-trimethyl-siloxycyclohexane and related systems. The acid-catalyzed rearrangement of bicyclo [5.1.0] octyl-8-methanol

Creator:: Walton, Edward Samuel
Abstract:: Part I The pyrolysis of cis- and trans- 1, 2-divinyl-1- trimethylsiloxy - cyclohexane, II- and III-TMS, under the same conditions as the pyrolysis of cis-l-vinyl -1-trimethylsiloxycyclooct-3-ene, I-TMS, confirms that a sequence of concerted reactions for the rearrangement of II- and III-TMS to trans-l-trimethylsiloxycyclodec-3-ene, IV-TMS, is a viable pathway in the...

Scaffold reactivity and large scale Synthesis of organocatalyzed Yamada-Otani Condensation product and investigation of the synthesis and properties of axially chiral 8,8'-biquinolyls and 8-(naphtha-1-yl)quinolines

Creator:: Banerjee, Somdev
Abstract:: In Part I, (4S,5R)-4,5-dimethyl-4-phenylcyclohex-2-enone (19a) was prepared in 73% yield with high enantio- and diastereo-selectivity (er > 98:2, dr > 20:1) on a multigram scale by a Yamada-Otani condensation between (E)-pent-3-en-2-one and 2-phenylpropanal catalyzed by a sulfonimide derivative of (S)-proline (18, HuaCat®). Synthetically useful transformations of the cyclohexenone product 19a...

Oxymercuration of cyclodeca-1,2,5,8-tetraene

Creator:: Hong, Pak-Kong
Abstract:: The reactions of cyclodeca-1, 2, 5, 8-tetraene with mercuric salts in solvents of varying nucleophilicity are described. Instead of forming the usual oxymercuration products reported for reactions of olefins and allenes with mercuric salts, the major products obtained in the present cases result from the initial electrophilic addition of the...

Gene Expression, Structure Elucidation, and Bioactivity of Aspergillus Natural Products

Creator:: Neuhaus, George F.
Abstract:: The study of natural products (NPs) and their application has shaped humanity. Starting with the idea of using plants as medicine, it has now grown into the science of purifying and identifying organic molecules from nature to study their inherent biological activities. Understanding the molecular structures of NPs is the...

The chlorination of uric acid by phosphorus oxychloride in the presence of certain aliphatic and aromatic amine hydrochlorides

Creator:: Haase, William Alan
Abstract:: Since the use of N, N-diethylaniline hydrochloride in the chlorination of uric acid with phosphoryl chloride seems to promote the reaction, a study of the effect of other salts of nitrogenous bases in the chlorination of uric acid was undertaken. When N, N-diethylaniline hydrochloride was used in lieu of the...

Identification of a product of the Friedel-Crafts cyclization of β -(3- cyclohexenyl) propionyl chloride

Creator:: McEwen, Terry Earl
Abstract:: An improved procedure for the preparation of β-(3-cyclohexenyl) propionic acid from 4-vinylcyclohexene was developed. The Friedel-Crafts cyclization of β-(3-(3-cyclohexenyl) propionyl chloride with aluminum chloride was shown to give one bicyclic chlorine containing ketone in 41% yield. This ketone was identified by a combination of spectral and chemical methods as a...
