agent, such as phosgene, thionyl chloride, or phosphorus oxychloride. The reaction was carried out in THF at −20–−30°C using triethylamine to neutralize the reaction solution exactly. Among the other N-protecting groups used in peptide chemistry, p-bromobenzyloxycarbonyl and p-chlorobenzyloxycarbonyl amino acids also gave the corresponding aziridinones quantitatively. Some of these N-acylated aziridinones
光学活性 3-取代-1-benzyloxycarbonylaziridin-2-ones 是由相应的 benzyloxycarbonyl L-氨基酸通过使用脱水剂(如光气、亚硫酰氯或磷酰氯)合成的。反应在-20--30°C的THF中进行,使用三乙胺精确中和反应溶液。在肽化学中使用的其他 N-保护基团中,对溴苄氧羰基和对氯苄氧羰基氨基酸也定量给出了相应的氮丙啶酮。这些N-酰化氮丙啶酮中的一些以结晶形式获得。还描述了反应机理。
