Abstract (AI)
-C-H hydroxylation of benzaldehydes. Directed by a transient imine group, the borylation of benzaldehydes, sequentially followed by the hydroxylation, furnishes diverse salicylaldehydes in a one-pot manner. The resultant salicylaldehydes could be readily applied in the downstream synthesis to produce bioactive molecules.
Key Findings
1
A novel one-pot protocol enables ortho-C–H hydroxylation of benzaldehydes to produce salicylaldehydes.
2
Resulting salicylaldehydes are readily applicable to downstream syntheses to produce bioactive molecules.
3
Sequential borylation followed by hydroxylation in the same reaction vessel furnishes diverse salicylaldehydes.
4
The method uses a transient imine directing group to guide borylation of benzaldehydes prior to hydroxylation.
