Hydroxyl-Directed Stereoselective Diboration of Alkenes
... conversion in a reasonable time frame, the reaction was run at a increased substrate concentration (0.5 M). After 12 h at 70 °C, followed by oxidative workup, triol 2 was obtained in 84% yield and as a 17:1 mixture of syn:anti diastereomers. Also in connection to synthesis utility, the ability to ad ...
