Site-selective oxidation of vicinal bis(boronates) is accomplished through the use of trimethylamine N-oxide in 1-butanol solvent. The reaction occurs with good efficiency and selectivity across a range of substrates, providing 2-hydro-1-boronic esters which are shown to be versatile intermediates in the synthesis of chiral building blocks.
LITHIATION OF THE BENZENE RING IN THE PRESENCE OF ortho-ALKYL SUBSTITUENTS BEARING ONE OR TWO HETEROATOMS ON THE β-CARBON. A CONVENIENT SYNTHESIS OF MELLEIN AND KIGELIN

The title reaction can be successfully accomplished by proton-metal exchange with n-butyllithium, and the usually observed elimination to a styrene derivative suppressed, provided an appropriate combination of heteroatoms bound to the β-carbon of the alky
