A novel variation of the boronicacid Mannich (BAM) reaction is described, in which α,α-dichloro- and α,α,ω-trichloroal-dehydes, morpholine, and arylboronicacids 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
