Facile synthesis of the azocino[4,3-b]indole framework of strychnopivotine and other Strychnos alkaloids
(Springer, 2016)
A new synthetic route to the 1,5-methanoazocino[4,3-b]indole is described. The aim of the present study is to provide a tetracyclic skeleton for the synthesis of pentacyclic Strychnos alkaloids (tubifolidine and ...
Selective oxidative deoximation with anhydrous Ce(IV) sulfate
(Pergamon-Elsevier Science Ltd, 2015)
Anhydrous Ce(SO4)(2) in chloroform selectively converts oximes into the parent carbonyl compounds in good yields. Hammett correlations helped to indicate a plausible mechanism for the above reaction. The formation of ...
Selective reduction of 1,4-diarylimidazoline-3-oxides to imidazolidin-1-ols and hydroxylamine derivatives
(Springer Wien, 2010)
C-2-unsubstituted imidazoline-3-oxides were reduced with NaBH4 in THF to give the corresponding trans-3,5-diarylimidazolidin-1-ols, while under the same conditions C-2-substituted derivatives gave the corresponding ...
Imidazolidin-1-oles, N-2-aminoethyl nitrones and 1,2,5-oxadiazinanes. A novel ring-chain tautomerism
(Pergamon-Elsevier Science Ltd, 2007)
Imidazolin-3-oxides I were reduced with NaBH4 in THF at reflux to give the corresponding 2,3,5-triarylimidazolidin-l-oles 2, which are proved to be in a ring-chain-ring tautomeric equilibrium with N-2-aminoethyl nitrones ...
