Mallik, Sumitava; Bhajammanavar, Vinod; Baidya, Mahiuddin published an article in 2021. The article was titled 《Regioselective Nitrosocarbonyl Aldol Reaction of Deconjugated Butyrolactams: Synthesis of γ-Heterosubstituted α,β-Unsaturated γ-Lactams》, and you may find the article in Asian Journal of Organic Chemistry.Application of 36016-38-3 The information in the text is summarized as follows:
The nitrosocarbonyl aldol reaction of deconjugated butyrolactams is developed employing quinidine as organocatalyst. The nitrosocarbonyl species generated in situ from hydroxamic acids react with a variety of deconjugated butyrolactams at room temperature, offering valuable α,β-unsaturated γ-lactams bearing heterosubstituted quaternary carbon center in very high yields. This nitrosocarbonyl aldol reaction is O-selective and proceeds exclusively at the γ-center of deconjugated butyrolactams. The reaction is scalable, accommodates diverse functional groups, and is also effective with azodicarboxylates. In the experiment, the researchers used many compounds, for example, N-tert-Butoxycarbonylhydroxylamine(cas: 36016-38-3Application of 36016-38-3)
N-tert-Butoxycarbonylhydroxylamine(cas: 36016-38-3) belongs to anime. Hydrogen peroxide (H2O2) and peroxy acids generally add an oxygen atom to the nitrogen of amines. With primary amines, this step is normally followed by further oxidation, leading to nitroso compounds, RNO, or nitro compounds, RNO2. Secondary amines are converted to hydroxylamines, R2NOH, and tertiary amines to amine oxides, R3NO.Application of 36016-38-3
