Ethyl 5-[(ethoxycarbonyl)oxy]-5,5-diphenylpent-2- ynoate
(2019-11-12)
The title compound, C 22 H22 O 5, crystallizes with two molecules in the
asymmetric unit, one of which shows disorder of its ethyl acetate group over
two sets of sites in a 0.880 (2):0.120 (2) ratio. The C C distances ...
Antimicrobial activity of different sodium and potassium salts of carboxylic acid against some common foodborne pathogens and spoilage-associated bacteria
Actividad antimicrobiana de diferentes sales de ácidos carboxílicos de sodio y potasio contra algunos microorganismos patógenos y de deterioro asociados a alimentos
(2018)
Cleaning and disinfection represent the most important activities associated with the elimination of dirt and microorganisms at food processing plants. Improper procedures may lead to cross contamination of food leading ...
Synthesis and preliminary determination of antibacterial activity of some 1,3-enynes
(2019)
The synthesis of five 1,3-enynes was performed and its activity against Gram-positive and Gram-negative bacteria was determined.
A New Method for the Preparation of 1,5-Diynes. Synthesis of (4E,6Z,10Z)-4,6,10-Hexadecatrien-1-ol, the Pheromone Component of the Cocoa Pod Borer Moth Conopomorpha cramerella
(2004)
A new method for the synthesis of 1,5-diynes, from the reaction of 1,3-dilithiopropyne and propargyl chlorides, was developed. This new methodology was used to prepare (4E,6Z,10Z)-4,6,10-hexadecatrien-1-ol, one of the ...
A new and efficient synthesis of (3E,8Z,11Z)-tetradeca-3,8,11-trienyl acetate, the major sex pheromone component of the tomato leafminer Tuta absoluta
(2018)
An efficient synthesis of (3E,8Z,11Z)-tetradeca-3,8,11-trienyl acetate, the major sex pheromone component of the tomato leafminer moth, Tuta absoluta, was accomplished. The synthesis started with but-3-yn-1-ol and gave an ...
Síntesis de la feromona sexual de la polilla de la papa, Scrobipalpopsis Solanivora
(1988)
Se sintetizó el acetato (E) -3- dodecenilo, atrayente sexual de la polilla de la papa (Scrobipalpopsis solanivora), utilizando dos procedimientos: una ruta acetilénica y mediante la condensación de Knoevenagel.
A facile method for the preparation of bishomopropargylic alcohols from acyl chlorides
(2014)
Controlled dilithiation of propargyl bromide with two equivalents of n-butyllithium, in the presence of
TMEDA, produces the operational equivalent of the dianion 1,3-dilithiopropyne. The latter reacts
efficiently with ...
Propargylation of Carbonyl Compounds: An Efficient Method for the Synthesis of Homopropargyl Alcohols
(1998)
Controlled dilithiation of allene, with two equivalents of n-butytlithium, produces the propargyl dianion 5. The latter couple efficiently with carbonyl compounds to produce homopropargyl alcohols in high yields.
5,5-Diphenyl-cis-penta-2,4-dienoic acid
(2019)
In the title compound, C17H14O2, the dihedral angle between the phenyl rings is 76.52 (7)°. In the crystal, pairwise O—H⋯O hydrogen bonds link the molecules into carboxylic acid inversion dimers.
1-Nitro-4-(1-propyn-1-yl)benzene
(2019)
The title compound, C9H7NO2, was prepared by alkynylation of 4-iodonitrobenzene with 1,3-dilithiopropyne in the presence of 1 equivalent of CuI and catalytic amounts of Pd(PPh3)2Cl2. The complete molecule is generated ...
