Synthetic studies using B-keto esters

1976
The dianions of β-keto esters have been generated using one equivalent of sodium hydride and one equivalent of n-butyl1ithium or two equivalents of lithium diisopropyl-amide. The reaction of these dianions with various epoxides was studied. On treatment of lithio sodio methyl aceto-acetate (55) with one and one-half equivalents of ethylene oxide and on

Synergism of antioxidants in synthetic ester oil

Chemistry and Technology of Fuels and Oils, 1966
1. A study has been made of the antioxidant effectiveness of [binary] mixtures of three phenolic inhibitors-2,6-di-tert-butyl-4-methylphenol, 4,4′-methylene-bis(2,6-di-tert-butylphenol), and 2,2′-methylene-bis(4-methyl-6-tert-butylphenol)- and of mixtures of these phenolic inhibitors with p-hydroxydiphenylamine and diphenylamine. 2.

Synthetic Cholesterol-Ester Antigens in Experimental Atherosclerosis

1967
It seems fairly well established, as the result of previous reports [1, 2, 3] and of work reviewed elsewhere in this symposium, that stimulation of the RES can influence some aspects of lipid metabolism. Early work by Weinhouse and Hirsch [4] on the composition of atherosclerotic plaques showed that the principal sterol fraction was the esterified form.

Synthetic peptide and ester substrates for rennin

Journal of Dairy Research, 1969
SummaryRennin hydrolysed the phe-met bond in the peptide H-ser-leu-phe-met-ala-OMe (i.e. methyl ester), the amino acid sequence of which is similar to that around the phe-met bond attacked by rennin in κ-casein. Rennin did not attack other peptides from this sequence not containing serine, and it is suggested that, in both κ-casein and the pentapeptide,

α‐Hydroxyboronate Esters: Formation and Synthetic Applications

Asian Journal of Organic Chemistry, 2015
AbstractThe synthesis of α‐oxyboronate esters by the copper‐catalyzed diboration of carbonyls provides a facile method to access these versatile intermediates. The evolution of diboration conditions and approaches to allow the isolation of products derived from α‐hydroxyboronate esters is discussed.
