A sequential, organocatalysed asymmetric reaction to access chiral 1,2-oxazines and chiral pyridazines is reported, which proceeds in moderate to good yields and good to excellent enantioselectivities.
Here we describe a highly enantioselective organocatalytic synthesis of chiral 3,6-dihydropyridazines from achiral starting materials which proceeds with good yield via a one-pot procedure.
