Abstract A novel variation of the boronic acid Mannich (BAM) reaction is described, in which α, α-dichloro-and α, α, ω-trichloroaldehydes, 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 group.
