(Texas A&M University. Libraries, 1978)The basic goal of this study was the development of an efficient approach to the total synthesis of vernolepin. Special attention was paid to the development of an efficient synthesis of bicycle[4.3.1]-dec-3-en-9,10-diones ...
-
(Texas A&M University. Libraries, 1992)Chapter II describes the synthetic application of a non-heme monooxygenase from Pseudomonas oleovorans (POM) toward the preparation of a series of epoxides from their protected allylic alcohol precursors. Like other ...
-
(Texas A&M University. Libraries, 1992)The synthetic utilities of enzymes as catalysts for asymmetric synthesis have been explored in several aspects. Fructose-1,6-diphosphate aldolase from rabbit muscle and E. coli, rhamnulose-1-phosphate aldolase and ...
-
(Texas A&M University. Libraries, 1987)Several aspects of the use of enzymes as catalysts in organic synthesis have been explored. The stability of the enzyme glucose dehydrogenase useful in reduced nicotinamide cofactor (NAD(P)H) regeneration has been studied. ...
-
(Texas A&M University. Libraries, 1990)Several aspects of the use of enzymes in organic synthesis have been explored. Fructose-1,6-diphosphate aldolase (FDP aldolase) is available commercially and has been cloned and overexpressed in E. coli. Both aldolases ...
-
(Texas A&M University. Libraries, 1992)Two of the key enzymes in the biosynthetic pathway of sialic acids were studied. A highly expressed CMP-sialic acid synthetase with a decapeptide tag attached at the C-terminal of the enzyme and the wild type enzyme from ...
-
(Texas A&M University. Libraries, 1989)A semi-automated vibrating tube densimeter designed for operations between 100 and 700 K and to 70 MPa is described. This densimeter features continuous flow of the sample fluid and a fluid conditioning system that rapidly ...
-
(Texas A&M University. Libraries, 1980)Hydroxyalkylation and acylation reactions of lithium enolates of amino acid derivatives 11-13 were investigated. Extensive rearrangement of 11 occurred under the reaction conditions. The lithium enolate of 12 exhibited ...
-
(Texas A&M University. Libraries, 1979)The behavior of self-associating bile acid esters in nonaqueous media have been investigated using spectroscopic techniques, principally ¹H and ¹³C nuclear magnetic resonance (nmr) spectroscopy, as well as thermodynamic ...
-
(Texas A&M University. Libraries, 1983)The generation and synthetic utility of azaallyllithium reagents from acyclic imidate esters was described. The acyclic imidate esters 5-15, 18-22, 31-33, 34, 36 and 37 were prepared by various methods. Azaallyllithium ...
-
(Texas A&M University. Libraries, 1993)A new, general method for the preparation of 5-aminoalkyl-furan-2(5H)-ones has been developed, and the details of the reaction have been studied. 5-Aminoalkylfuran-2(5H)-ones, which contain two chiral centers, were synthesized ...
-
(Texas A&M University. Libraries, 1986)Both cross-linked polystyrene and linear ethylene oligomers were investigated as supports for reagents and catalysts. Use of either of these polymers as supports, reagents or catalysts had certain advantages. Selection of ...
-
(Texas A&M University. Libraries, 1986)Ethylene oligomers having diphenylphosphine, diaryl and triaryl phosphite functional groups were used as supports for hydrogenation, hydroformylation and diene cyclooligomerization catalysts. An advantage of these ethylene ...
-
(Texas A&M University. Libraries, 1978)The synthesis of thiosugars containing several diorganylarsino groups is described. The compounds prepared are: dihexadecyl-, di-n-octyl-, dicyclohexyl-, dibutyl-, dipropyl-, diethyl-, methyl-npropyl- and 2-hydroxyethylm ...
-
(Texas A&M University. Libraries, 1978)A detailed NMR study has been made into the preparation, structure and characterization of a series of 1,7,7-trimethyl-2,3-benzobicyclo[3.3.1]non-2-enes. This family of compounds was derived from the parent structure, A, ...
