一种含不饱和烯的α-酰氧基酮的合成方法
摘要：
本发明公开了一种含不饱和烯的α‑酰氧基酮的合成方法，该方法是在空气环境下，肉桂酸、苯丙酮及有机过氧化物，在亚铜盐/四烷基溴化铵催化体系中，通过一锅反应合成含不饱和烯的α‑酰氧基酮；该方法首次成功地通过α，β肉桂酸和苯丙酮直接合成含不饱和烯的α‑酰氧基酮，具有高选择性、高产率、反应条件温和、步骤简单等特点，有利于工业化生产。
摘要（英）：

The invention discloses a method for synthesizing Alpha-acyloxyone containing unsaturated alkenes, comprising: in air environment, subjecting cinnamic acid, propiophenone and organic peroxides, in cuprous salt/tetraethylammonium bromide catalytic system, to one-pot reaction to synthesize the Alpha-acyloxyone containing unsaturated alkenes; it is the first time for the invention to directly synthesize Alpha-acyloxyone containing unsaturated alkenes successfully through Alpha,Beta-cinnamic acid and propiophenone; the method has high selectivity, high yield, mild reaction conditions, simple steps and other advantages, and facilitates industrial production.
