substituted amino phosphonates using a series of palladium-catalyzed reactions. The judicious selection of nitrogen nucleophile and palladium catalyst allow for excellent regio- and stereochemical control. Palladium(0)-catalyzed amine addition or tosyl carbamate rearrangement gives rise to the γ-substituted phosphonates, whereas, reaction of tosyl carbamates with palladium (II) and base gives oxazolidinones
使用一系列钯催化的反应,将烯丙基羟基膦酸酯转化为β和γ取代的氨基膦酸酯。氮亲核试剂和钯催化剂的明智选择可以实现出色的区域和立体化学控制。钯(0)催化的胺加成或甲苯磺酸氨基甲酸酯重排产生γ-取代的膦酸酯,而甲苯磺酸氨基甲酸酯与钯(II)和碱的反应产生恶唑烷酮(β-取代)。
