A novel variation of the boronic acid Mannich (BAM) reaction is described, in which α,α-dichloro- and α,α,ω-trichloroal-dehydes, morpholine, and arylboronic acids are used. During this one-pot reaction in refluxing toluene, 1 -phenyl- 1-morpholinoalkan-2-ones form in moderate yields. The dichloromethylene group is formally converted into a ketone functionality and as such acts as a masked carbonyl
描述了硼酸曼尼希 (BAM) 反应的一种新变体,其中使用了 α,α-二氯和 α,α,ω-三氯醛、吗啉和芳基硼酸。在回流甲苯中的这一单锅反应期间,1-苯基-1-吗啉代烷-2-酮以中等收率形成。二氯亚甲基正式转化为酮官能团,因此充当掩蔽羰基。
