The Effects Of Electron-Donating And Electron-Withdrawing Groups On The Alkylation Sites Of Para-Substituted Phenylacetones, Abraham L. Faburada Aug 1978

The Effects Of Electron-Donating And Electron-Withdrawing Groups On The Alkylation Sites Of Para-Substituted Phenylacetones, Abraham L. Faburada

Masters Theses

The dianions of phenylacetone and its para-substituted derivatives were generated using potassium hydride and n-butyl lithium in tetrahydrofuran. Methyl, ethyl, and n-butyl iodides were used to alkylate the dianions. The results of alkulation indicated that C1 is preferentially attacked by the less active ethyl and n-butyl iodides. The results further show that terminal alkylation is enhanced by electron-donating groups at the para-position of the phenyl ring. The results are rationalized in terms of the difference in electron density at C1 and at C3 in the dianion, on the basis of resonance theory. The regio-selectivity of alkylation as …

Studies In Syntheses Of Non-Isoprenoid Sesquiterpenes, Raojibhai Javerbhai Patel Jan 1969

Studies In Syntheses Of Non-Isoprenoid Sesquiterpenes, Raojibhai Javerbhai Patel

Masters Theses

The purpose of this study was to find the shortest route to prepare the 1,9-dimethyl decalone system I, a key intermediate in the synthesis of non-isoprenoid sesquiterpenes. The decalone system I was prepared in good yield by dehydrating the hydroxyketone II with 50% H2SO4. The dehydration of hydroxyketone II was also affected by heating in the presence of iodine crystals to yield 80% of the decalone system I.

The basic kinds of approaches under investigation were the Diels-Alder reaction and the Robinson annellation. The Diels-Alder reaction between the conjugated diene, 1-acetoxybutadiene (III) and 2,3-dimethylcyclohexenone (IV) under …
