Surprisingly, the intramolecular reaction was not reported until 1991 but has become important in the synthesis of natural products. This article is cited by 6.15 Hofmann, Curtius, Schmidt, Lossen, and Related Reactions. Total Synthesis of (±)-Parvineostemonine. Get article recommendations from ACS based on references in your Mendeley library. The Schmidt reaction of carboxylic acids, which produces amines, is in direct competition with the milder Curtius rearrangement, and is rarely used in practice. Organic Chemistry by Jonathan Clayden, Nick Greeves, Stuart Warren2. It is named after Karl Friedrich Schmidt (1887–1971), who first reported it in 1924 by successfully converting benzophenone and hydrazoic acid to benzanilide. Schmidt rearrangement 1. HN3 or NaN3 HN3, H+, D The Curtius Rearrangement R Cl O RNH2-CO2 NaN3, D The Hoffman is very similar to the Schmidt/Curtius, only the common acyl nitrene intermediate is generated from the oxidation of a primary amide. the Altmetric Attention Score and how the score is calculated. 41 publications. You’ve supercharged your research process with ACS and Mendeley! Schmidt Reaction. Yu-Ming Zhao, Peiming Gu, Yong-Qiang Tu, Chun-An Fan and Qingwei Zhang. Yadagiri Thigulla, Santosh Ranga, Subhas Ghosal, Jayanty Subbalakshmi, Anupam Bhattacharya. [1] Often a substituent moves from one atom to another atom in the same molecule. The intermediate is isocyanate. The American Chemical Society holds a copyright ownership interest in any copyrightable Supporting En Zhang, Yong-Qiang Tu, Chun-An Fan, Xiong Zhao, Yi-Jun Jiang and Shu-Yu Zhang. Formal Syntheses of (±)-Stemonamine and (±)-Cephalotaxine. Similar to a rearrangement, a carbon–nitrogen bond was broken through formation of an aziridinium species in the next example. In the example below the substituent R moves from carbon atom 1 to carbon atom 2: − | − − − − − | − − These metrics are regularly updated to reflect usage leading up to the last few days. SCHMIDT REARRANGEMENT Touseef Haidar 2. Contoso S u i t e s Schmidt Reaction The Schmidt reaction is an organic reaction in which an azide reacts with a carbonyl derivative, usually a aldehyde, ketone, or carboxylic acid, under acidic conditions to give an amine or amide, with expulsion of nitrogen. Often a substituent moves from one atom to another atom in the same molecule. Please note: If you switch to a different device, you may be asked to login again with only your ACS ID.

Total Synthesis of (±)-Maistemonine, (±)-Stemonamide, and (±)-Isomaistemonine. A rearrangement reaction is a broad class of organic reactions where the carbon skeleton of a molecule is rearranged to give a structural isomer of the original molecule.
