Synthesis of α-Substituted Enoximes with Nucleophiles via Nitrosoallenes
摘要:
This paper reports nitrosoallene-mediated synthesis of alpha-substituted enoximes. Nucleophilic substitution of nitrosoallenes, a novel chemical species prepared from allenyl N-hydroxysulfonamides, afforded alpha-functionalized enoximes. Introduction of various nucleophiles proceeded smoothly to form C-N, C-O, C-S, C-F, and C-C bonds in the presence of azodicarboxylates.
