Nitrosoaldol reaction between alkenyl trichloroacetates and nitrosobenzene
has been achieved using dibutyltin dimethoxide as a catalyst, which
is regenerated in the presence of methanol. The corresponding α-hydroxyamino
ketones (N-adducts) have exclusively formed not only from cyclic
alkenyl trichloroacetates but also from acyclic ones.
