标题:New Practical Synthesis Of Indazoles Via Condensation Of O-Fluorobenzaldehydes And Their O-Methyloximes With Hydrazine
摘要:The Reaction Of O-Fluorobenzaldehydes And Their O-Methyloximes With Hydrazine Has Been Developed As A New Practical Synthesis Of Indazoles. Utilization Of The Methyloxime Derivatives Of Benzaldehydes (In The Form Of The Major E-Isomers) In This Condensation Effectively Eliminated A Competitive Wolf-Kishner Reduction To Fluorotoluenes,Which Was Observed In The Direct Preparations Of Indazoles From Aldehydes. Reaction Of Z-Isomers Of Methyloximes With Hydrazine Resulted In The Formation Of 3-Aminoindazoles Via A Benzonitrile Intermediate.
