Chemo-, regio-, and stereoselective hydroboration of conjugated enyne alcohol/amine: facile synthesis of Z,Z-/Z,E-1,3-dien-1/2-ylboronic ester bearing hydroxyl/amino group

Chemo-, regio-, and stereoselective hydroboration of conjugated enyne alcohol/amine has been realized through catalyst combination-CuCl/PCy3/NaOtBu, providing facile access to Z,Z- or Z,E-1,3-dien-1/2-ylboronate bearing hydroxyl/amino groups.75
