The retro-ene reaction of 2-vinylcyclohexanols and approaches to the synthesis of botryococcene

Creator:: Rusay, Ronald Joseph
Abstract:: The retro-ene reaction of 2-vinylcyclohexanols occurs readily in the vapor phase at 400-450° producing unsaturated carbonyl compounds in good yields. The starting- materials were prepared in general by the carbenoid addition reaction of ethyl diazoacetate, appropriately substituted cyclohexene, and copper catalyst to produce bicyclic esters which were reduced to the...

Intramolecular transfer of complexed radicals as a possible explanation for long-range substituent effects observed in hydrogen abstraction reactions

Creator:: Newkirk, David Dudley
Abstract:: The relative rates of hydrogen abstraction from 1-phenylalkanes and a,w-diphenylalkanes using N-bromosuccinimide and bromotrichloromethane were determined at 70°C. In both cases the reactions were photoinitiated. Only benzylic bromination was observed. The 1-phenylalkanes reacted with both reagents to give rates largely independent of substrate. Similarly, the rate of the reaction between...

The study of the influence of the nitro substituent on the hydrazinolysis of certain substituted 5-nitropyrimidines

Creator:: Stahl, Quade Russell
Abstract:: The unique reaction between 4, 6-dimethoxy-5-nitropyrimidine and methylhydrazine was investigated. The reaction product was identified as 4-hydrazino-6-hydroxypyrimidine from (a) spectral data, (b) by direct synthesis of the product via 4-chloro-6-hydroxypyrimidine and hydrazine, and (c) by conversion of the product to the known 4-amino-6-hydroxypyrimidine using Raney nickel. The product was not...

The preparation and reactions of 1-(2-pyridyl)-3-menthyl-3-butene-2-ol and 1-(2-pyridyl)-4-methyl-3-butene-2-ol

Creator:: Janposri, Sompong
Abstract:: 1-(2-pyridyl)-3-methyl-3-butene-2-ol was prepared by allowing 2-picolyllithium to react with methacrolein. In the reaction of picolyllithium with crotonaldehyde, two products 1-(2-pyridyl)-4-methyl-3-butene-2-ol and 1-(2-pyridyl)-4-methyl-2-butene-4-ol were formed. 1-(2-pyridyl)-3-methyl-3-butene-2-ol was subjected to the low pressure hydrogenation, using methanol as solvent and PtO₂ as catalyst. A red yellow liquid 1-(2-pyridyl)-3-methyl-2-butanol was obtained. Derivatives of the...

Preparation and reactions of 7-bicyclo [3.3.1] nonen-2-one

Creator:: Salisbury, Kirby Grant
Abstract:: 2-Carboxy-3(3-cyclohexen-1-yl)propionic acid, 3-(3-cyclohexen-1-yl)propionic acid and 3-(3-cyclohexen-1-yl)propionyl chloride were prepared in sequence from ethyl-2-carbethoxy-3-(3-cyclohexen-1-yl)propionate. Cyclization of 3-(3-cyclohexen-1-yl)propionic acid in polyphosphoric acid resulted in the formation of 4, 5, 6, 7-tetrahydroindanone which was identified by its ultraviolet spectrum and its physical properties. 7-Bicyclo[3.3.1] nonen-2-one was prepared by a Friedel-Crafts cyclization of 3-(3-cyclohexen-1-yl)-propionyl...
