ATTEMPTED PREPARATION OF N-SUBSTITUTED DIPHENYLCYCLOPROPENEIMINE N-OXIDE
The reaction of diphenylcyclopropenone with several N-substituted hydroxylamine and primary amines are investigated. Most of these reactions led to ring opened or ring enlarged products, instead of the desired N-Oxide or imine. The reaction of cyclopropeneimine with peracid-another possible route to N-substituted cyclopropeneimine N-Oxide is studied. Most of the unexpected products are ide...
متن کامل2-(Benzylsulfanyl)pyridine N-oxide
In the title compound, C(12)H(11)NOS, the dihedral angle between the oxopyridinium and phenyl rings is 58.40 (1)°. The crystal structure is stabilized by C-H⋯O hydrogen bonds, π-π stacking inter-actions involving the pyridinium rings [centroid-centroid distance = 3.6891 (9) Å] and C-H⋯π inter-actions.
متن کاملA DFT study of the reactivity of actinidocenes (U, Np and Pu) with pyridine and pyridine N-oxide derivatives.
The ortho C-H bond activation of several pyridine and pyridine N-oxide derivatives mediated by Cp(2)An(IV)(CH(3))(2) and Cp(2)An(III)(CH(3)) (Cp = C(5)H(5) and An = U, Np, Pu) have been investigated at the DFT level. For uranium(IV) complex, an excellent agreement with experimental observations is found, and particularly in the case of 2-picoline where only ortho sp(2) C-H activation is observe...
متن کاملFacile preparation of alpha-amino ketones from oxidative ring-opening of aziridines by pyridine N-oxide.
The oxidative ring-opening reaction of a variety of activated aziridines by pyridine N-oxide provided alpha-amino ketones or alpha-amino aldehydes in good yields.
متن کاملPyridine N-oxide derivatives: unusual anti-HIV compounds with multiple mechanisms of antiviral action.
Pyridine N-oxide derivatives represent a new class of anti-HIV compounds, for which some members exclusively act through inhibition of HIV-1 reverse transcriptase and thus characteristically behave as non-nucleoside reverse transcriptase inhibitors. Other members act, additionally or alternatively, at a post-integrational event in the replication cycle of HIV, that is, at the level of HIV gene ...
