Full chirality transfer in the conversion of secondary alcohols into tertiary boronic esters and alcohols using lithiation-borylation reactions

Bagutski, Viktor,French, Rosalind M.,Aggarwal, Varinder K.

supporting information; experimental part, p. 5142 - 5145 (2010/10/20)

New conditions, full transfer: Using MgBr2/MeOH as an additive now provides essentially 100 % retention of configuration in the lithiation-borylation reaction, thus leading to tertiary boronic esters (or tertiary alcohols) with exceptionally hi
