WebSynthesis of Acyl Phosphoramidates Employing a Modified Staudinger Reaction Author: Iain Currie, Brad E. Sleebs Source: Organic letters 2024 v.23 no.2 pp. 464-468 ISSN: 1523-7052 ... The reaction scope was extended to include the synthesis of imidodiphosphates and the natural product Microcin C. Agid: 7236095 WebA one-step synthesis of acyl phosphoramidates from a variety of functionalized acyl azides has been developed employing trimethylsilyl chloride as an activating agent in a modified Staudinger reaction. The methodology was further adapted to include the in situ generation of the acyl azides from a diverse selection of carboxylic acids and ...
