PROCESS OF FORMING A PYRROLE COMPOUND

Disclosed is a process of forming a pyrrole compound. The process comprises contacting an α-carbonyl oxime compound 1 and an α,β-unsaturated aldehyde 2 R1 and R2 in compound 1 are independently selected from the group consisting of H

Unusual domino Michael/aldol condensation reactions employing oximes as N-selective nucleophiles: Synthesis of N-hydroxypyrroles

(Figure Presented) A facile synthesis of N-hydroxypyrroles has been developed using readily available α-carbonyl oximes and α,β-unsaturated aldehydes. The domino reaction proceeds through iminium activation of α,β-unsaturated aldehydes, Michael addition u

Method for preparing trion-bis(oxime ether) derivatives andrion-mono and trion-bis(oxime ether) derivatives obtained therewith

The present invention relates to a method for the production of trion-bis(oxime ether) derivatives of formula (I), wherein the substituents have the following meaning: R1, R3represent unsubstituted, partially or totally halogenated C1-C6-alkyl or C3-C6-cycloalkyl; R2, R4represent C1-C4-alkyl or a methyl substituted by C2-C4-alkenyl, C2-C4-alkinyl or phenyl and X represents oxygen or N—OH. The invention also relates to the intermediate products obtained with said method.

Synthesis of some new 1-hydroxypyrazole-2-oxides and heterocyclic oximes

α,β-Unsaturated oximes (Ia-c) are converted into 1-hydroxypyrazole-2-oxides (IIIa-c) and isoxazole (IV) by reaction with n-butyl nitrite and metal ions in pyridine.Reduction of IIIc with zinc in acetic acid furnishes the pyrazole V.However, reduction of IIIc with sodium dithionite yields the 1-hydroxypyrazole (VI).Acylation of IIIc affords the acyl derivative (VII).Reaction of hydroxylamine hydrochloride and benzaldehyde with oximes VIIIa,b and IXa,b affords O-methyloximinoisoxazoles (Xa,b).
