WebOct 10, 2024 · The precursor intermediates, diethyl substituted phosphoramidites 3 (a–b) were prepared initially by a reaction of various amines 1 (a–b) and diethyl phosphorochloridite (2) and then they were treated by in situ with aromatic/alkyl azides through Staudinger reaction to accomplish title products. WebIn general, phosphoramidites are more stable than their phosphorochloridite counterparts and, in most cases, are relatively easy to prepare, store, and separate via chromatography, though a variety of phosphoramidites with orthogonal phosphorous-protecting groups are already commercially available. 212,213 Phosphoramidites have been extensively …
