Scyllo-inositol as a convenient protecting group for aryl boronic acids in Suzuki-Miyaura cross-coupling reactions

- Aryl boronic acids formed stable borate complexes with scyllo-inositol in hot water.
- The complexes showed poor reactivity in Suzuki-Miyaura cross-coupling reaction.
- Scyllo-inositol could be a novel reagent for protecting aryl boronic acids.
