NEW MATERIAL:α-Substrituted amino-ε-caprolactams of formula I (R1 is formula II; R2 is H, formula II).
EXAMPLE: α-Glycidylamino-ε-caprolactam.
USE: Agricultural chemicals, raw materials for polymers and intermediates of various kinds of compounds.
PREPARATION: For example, α-aminocyclohexanone oxime hydrochloride is subjected to Beckmann rearrangement to form α-amino-ε-caprolactam, which is made to react with epichlorohydrin to give α-(3-chloro-2-hydroxypropylamino)-ε-caprolactam of formula III. The product is dehydrochlorinated to produce the objective compound of formula I.
