Staudinger ligation chemistry

WebStaudinger-Bertozzi ligation. A nucleophilic phosphine attacks the organic azide, the product of which rearranges to form a four-membered transition state. Upon the release of N 2, the nitrogen attacks carbonyl group to form a five-membraned ring intermediate whose hydrolysis yields a stable amide bond. WebJun 23, 2024 · The logic behind click chemistry is simple: (i) new molecular properties are needed everywhere; (ii) such properties can emerge from the joining of small molecular building blocks; (iii) scientists and engineers not trained in synthetic chemistry often lack the skills and equipment needed to perform such connecting operations reliably; and (iv) …
