Websodium azide was found to give benzoyl azide ( 4), as shown in Scheme 1. Although this reaction proceeded in two steps from benzoic acid (1), I thought that the acyl phosphate 6 would be temporally formed if the phosphorazidate 5 were used in place of the phosphorochloridate 2, and the acyl phosphate 6 would react in situ with the azide ion … WebNov 6, 2024 · Here, we describe an efficient and selective protocol for straightforward access to a series of 5-((diarylphosphoryl)methyl)oxazolidin-2-ones via the copper-catalyzed difunctionalization of the C≡C bond of propargylic amines with CO 2 and phosphine oxide. Notably, copper catalysis is a sustainable and benign catalytic mode.

WebStable azide-transfer agent. In the presence of an amine, carboxylic acids are converted to acyl azides which undergo a modified Curtius reaction in the presence of an alcohol to give alkyl carbamates directly. With t-butanol, the resulting t-butyl carbamates can readily be converted to the free amines with mild acid.
