proceeds with complete net retention of configuration, and surprisingly, suffers from a regiochemical complication arising mainly from the unexpected competition of the [2,3]- vs. [1,2]-shift in the Wittig process, as revealed by the use of the deuterium-labeled substrate.
标题为σ的序列在构型的完全净保留下继续进行,并且令人惊讶地,它遭受区域化学并发症的困扰,这主要是由于Wittig过程中[2,3]-[1,2]-移位的意外竞争所致,通过使用氘标记的底物。
