For several years ago, several epoxide derivatives have been prepared using different methods; however, some protocols use reagents which could be expensive and require specials conditions. The aim of this investigation was to prepare two new epoxide‐derivatives from 3‐ethynylaniline using some reactions such as oximation, acetylation, 2 + 2 addition, functionalized chloroamides, and epoxidation via
A process for producing an oxime derivative, which comprises protecting the hydroxyimino group of an oxime compound with a protecting agent, subjecting the protected oxime compound to a given reaction, and thereafter deprotecting the reaction product, wherein a 2-alkenylating agent is used as the protecting agent.
