Which of the following compounds are cleaved by HIOX4 under mild conditions?
A2,3-dimethylbutane-2,3-diol
Bpropane-1,3-diol
C2-hydroxypropanoic acid
Dpropane-1,2,3-triol
Answer: A, C, D
Pinacol, lactic acid (alpha-hydroxy acid) and glycerol all contain adjacent oxygen-bearing carbons. Propane-1,3-diol has its OH groups separated by a CH2, so no cyclic periodate ester forms and it is not cleaved.
