A new application of amido-functionalized allylboronates to asymmetric 1,4-addition in water has been developed. Extremely high enantioselective 1,4-addition was achieved by employing N-mesityl maleimide as a substrate under CuSO4/bis(oxazoline) catalysis, affording the adduct with >99% ee.

Hydroxylactams prepared from N-carbonyl phthalimides and β-amido functionalized allylboronates underwent ring opening-asymmetric reclosure in the presence of catalytic amounts of MgBr2 and a chiral aminophenol to afford the corresponding N,O-spirocyclic compounds in excellent yields and high enantioselectivities.
