were also conducted, but resulted in decomposing the products during
purification by silica gel column.

(15) We used various silyl protecting groups (Me3Si to BnMe2Si to
Ph2MeSi) to facilitate the isolation and the HPLC analysis. We chose
the silyl protecting group with two intentions in mind. One is to
enable UV detection for aldehydes without UV-detectable functional
group, by attaching a UV detectable protecting group. The other is to
ensure clean peak separation during HPLC analysis. For example, in
the HPLC analysis of chiral organoboronate 3a, using the BnMe2Si
group enabled better peak separation in comparison to when it was
protected using other silyl groups. During the submission process of
this paper, a similar silylation procedure for isolating the aldehyde
borylation product was reported by Clark and co-workers, see: Moore,
