A process central to generation of inflorescence architecture diver- sity is inflorescence branching, with a major distinction between simple inflorescences, as in Arabidopsis, where flowers derive from the primary inflorescence axis (Fig. 1a,b,c), and compound inflores- cences, where flowers form...
氨基甲酸苄酯在强酸性条件下容易去保护。HBr/HOAc是酸解脱除苄氧羰基的最常用的试剂。脱除反应主要按下式进行。反应需要消耗2分子的HBr,Cbz的脱除速度随HBr浓度的增大而增大,因此实际上都是采用高浓度的过量HBr/HOAc溶液(1.2M-3.3M)以保证反应的完全。
