Abstract New chiral aminoamidoximes were prepared from (L)-proline, (L)-alanine, and (L)-isoleucine by treatment of the corresponding aminonitriles with hydroxylamine in the presence of triethylamine. The intramolecular cyclization with α-bromoacid chlorides and aldehydes was investigated to give new 1,2,4-oxadiazin-6-ones and 1,2,4-oxadiazoles, respectively. These compounds were likely to undergo
摘要 通过在三乙胺存在下用羟胺处理相应的氨基腈,由 (L)-脯氨酸、(L)-丙氨酸和 (L)-异亮氨酸制备了新的手性氨基酰胺肟。研究了与 α-溴酰氯和醛的分子内环化反应,分别得到了新的 1,2,4-oxadiazin-6-ones 和 1,2,4-oxadiazoles。这些化合物很可能通过氧和氮进行分子间环化。然而,即使在改变反应条件后,通过两个氮原子的分子内环化也没有发生。图形概要
