说明

一般說明

Diallyl pyrocarbonate or (Alloc)₂O is used as a reagent for the introduction of allyloxycarbonyl (Alloc or Aloc) protecting group to primary and secondary amines. In peptide synthesis, it is also used to protect amino acid functional groups due to its stability to the acidic and basic conditions. Various amino functional groups such as amino sugars and nucleosides are also protected by using diallyldicarbonate reagent.

其他說明

便于引入 N-烯丙氧基羰基 (N-Alloc) 氨基保护的试剂；烯丙基氨基甲酸酯保护易受钯(0)试剂裂解。
