Aldehydes 5, 7, and 9 derived from easily accessible (R)-2,3-cyclohexylideneglyceraldehyde 1 were used as novel substrates to obtain both syn- and anti-1,3-diols in several individual reactions by subjecting each of them to some practically viable metal-mediated Barbier-type allylations under moist conditions. In this regard, a detailed investigation was made regarding the compatibility and stereoselectivity
