Asian Journal of Organic Chemistry 2022, 11, e202100773. (DOI: 10.1002/ajoc.202100773)
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.

Development of new catalytic enantioselective formation of methylenelactam-based N,O-spirocyclic compounds via ring opening-asymmetric reclosure of hydroxylactams
Tetsuya Sengoku, Ayako Miyoshi, Tamaki Tsuda, Toshiyasu Inuzuka, Masami Sakamoto, Masaki Takahashi and Hidemi Yoda
Tetrahedron, 2020, 76, 131252. (DOI: 10.1016/j.tet.2020.131252)
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.

Zinc Hydroxide‐Catalyzed Asymmetric Allylation of Acetophenones with Amido‐Functionalized Allylboronate in Water
Tetsuya Sengoku, Ryunosuke Maegawa, Hiroki Imamura, Mitsuo Wada and Hidemi Yoda
Advanced Synthesis & Catalysis, 2020, 362, 2397-2418. (DOI: 10.1002/adsc.202000195)
Enantioselective reaction of water‐stable amido‐functionalized allylboronates with acetophenone derivatives in water is reported. The reaction was catalyzed with zinc hydroxide and a didecylamino‐functionalized chiral aminophenol reagent, affording a variety of homoallylic alcohols in up to 99% yield. The enantiomeric excess of the product reached up to 98%.
