(4R)-3-Allenyl-4-(diphenylmethyl)-oxazolidin-2-one, an unsubstituted allenamide

The first X-ray structure of an unsubstituted allenamide, C 19H17NO2, is reported. The solid-state phase supports the notion that a key minimum conformation of allenamides can be invoked to rationalize the observed stereochemical outcomes in many of our methodological studies employing allenamides. This minimum conformation involves two important factors, i.e. having approximate coplanarity between the planes of the oxazolidinone ring and the internal olefin, and having the allene moiety facing away from the carbamate carbonyl group. The C-N-C=C torsion angle that quantifies this approximate coplanarity between the plane of the oxazolidinone ring and that of the internal olefin, as determined from this crystallographic study, is -19.1 (2). A minimized structural calculation, which determined this angle to be -16.1, is in close agreement. Additional structural features include a probable pi-pi interaction between the allene moiety and a benzene ring, and non-classical hydrogen bonding in the form of weak C-H…O interactions that are responsible for the formation of two-dimensional networks.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 173604-33-6 is helpful to your research. Related Products of 173604-33-6

Synthesis of a beta-hexapeptide from (R)-2-aminomethyl-alkanoic acids and structural investigations

The (R) alpha-branched beta-amino acid derivatives 3-5 with the side chains of alanine, valine and leucine are prepared by amino-methylation of acyloxazolidinones 2a-c and are used for the synthesis of the trifluoroacetate salt 9 of H(-beta2-HVal-beta2-HAla-beta2-HLeu) 2-OH. The CD spectrum of compound 9 is compared with that of the isomer H(-beta3-HVal-beta3-HAla-beta3-HLeu) 2-OH (1) built from the corresponding beta-branched beta-amino acids.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 145589-03-3, you can also check out more blogs about145589-03-3

Total synthesis of (-)-ulapualide A: The danger of overdependence on NMR spectroscopy in assignment of stereochemistry

Lessons learnt: The asymmetric total synthesis of the macrolide (-)-ulapualide A has been accomplished. Interestingly, the 1H NMR spectrum and chiroptical data of the macrolide and of a previously synthesized diastereoisomer with opposite stereocenters at C3, C28, C29, C30, and C32 were superimposable, which highlights the care that must be taken in the assignment of configurations to complex structures based on NMR spectroscopy.
