The replacement of non-bridging sulfur in five-membered cyclic phosphorothioates by oxygen nucleophiles in the presence of bromine occurs with retention of configuration and has allowed the 31P NMR signals of the diastereoisomeric tert-butyldiphenyl silyl esters of 2′,3′-cyclic adenosine monophosphate to be assigned.
在溴存在下,五元环状硫代磷酸酯中的非桥连硫被氧亲核试剂取代,并保留了构型,并允许2',3'-环的非对映异构叔丁基二苯基甲硅烷基酯的31 P NMR信号要分配的腺苷一磷酸。
