摘要: C(α),O-Dilithiooximes were condensed with aldehydes and ketones to give β-hydroxyoximes which usually isolated characterized. These materials could be acid-cyclized the 2-isoxazoline. When dianion was p-anisaldehyde, it not necessary isolate intermediate; direct acid-cyclization after condensation led
