1,1,2,2-Tetraphenyl-1,2-ethanediol: A new protecting group for the synthesis of cyclopropylboronic esters
Pietruszka, J?rg,Witt, Andreas
, p. 91 - 94 (2007/10/03)
While enantiomerically pure auxiliaries and protecting groups for boronic acids are well established, much less attention has been paid to achiral derivatives. The commercially available benzpinacol (9) proved to yield highly stable boronic esters. The ne
