Intramolecular acid-catalyzed amide isomerization in aqueous solution.

[reaction: see text] We report for the first time that stoichiometric and even catalytic quantities of weak acids in aqueous solution can very efficiently catalyze amide isomerization in a carefully designed system in which a proton donor is situated so that intramolecular hydrogen bonding to the amide nitrogen is highly favored. Our results provide the first experimental verification that hydr...

DFT Study on the Possible Intramolecular Rearrangement of Four Monocyclic Monoterpenes

As the basis and preliminary work of future experimental study on PAHs formation under high temperature, theoretical computations on the intramolecular rearrangement reactions of sylvestrene (1-methyl-3-vinylcyclohexene) and 1,4-dimethyl-4-vinylcyclohexene are conducted and reveal that they may be transformed to themselves. The conversion between Dipentene and 2,4-dimethyl-4-vinylcyclohexen...

Acid Catalyzed Isomerization of Large Ring Bicyclic Alkenes: a Reevaluation of Some Betweenanene Synthetic Strategy

We recently described a remarkable acid-catalyzed isomerization of bicyclic alkenes Ia and Ib to the betweenanenes IIa and IIb. ’ This finding suggested that certain larger ring betweenanenes might possess unusual stability relative to double bond isomers and might thus be derivable from readily available bicyclic compounds via equilibrating processes. In this report we describe several attempt...

Nonenzymatic isomerization of 9-cis-retinoic acid catalyzed by sulfhydryl compounds.

Certain thiol-containing compounds catalyze, in a chemical reaction, the isomerization of 9-cis-retinoic acid to a mixture of all-trans-retinoic acid, 9-cis-retinoic acid, 13-cis-retinoic acid, and 9,13-dicis-retinoic acid. In the presence of such catalysts, all-trans-retinoic acid gives rise to the same mixture. Reactions approaching equilibrium contain more all-trans-retinoic acid than either...

Lewis Acid Catalyzed Z to E Isomerization of 1,2-Bis(diphenyl- phosphino)ethene

Z-1,2-Bis(diphenylphosphino)ethene, cis-Ph2PCH=CHPPh2, forms 1:2 adducts with GaBr3 and GaI3, the former of which has been identified in an X-ray diffraction study as the complex of the isomerized ligand, E-Ph2PCH=CHPPh2. The GaI3 complex is believed to be analogous on the basis of analytical and spectroscopic data. InBr3 affords a 1:1 complex with an ionic structure [(Ph2PCH=CHPPh2)2InBr2] [In...
