An Efficient Synthesis of 3-Phosphorylated Benzoxaboroles via the Pudovik Reaction
Keyword(s):
A simple, fast and efficient synthesis of 3-phosphorylated benzoxaboroles using the Pudovik reaction is reported. A number of diverse 3-(dialkoxyphosphoryl)-1-hydroxy-3H-2,1-benzoxaboroles were synthesised in 70–86% yield. Interesting hydrogen bond features were observed in the crystal lattice of the 5-chlorinated 3-bis(benzyloxy)phosphoryl derivative with both inter- and intramolecular C–H···O hydrogen bonds. Additionally, linear chains of intermolecular O–H···O hydrogen bonds were observed.
