catalytic parallelkineticresolution of unsymmetrical acyclic aliphatic syn-1,3-diol derived acetals mediated by chiral phosphoric acid. This method provides stereoselective access to a variety of syn-1,3-diols as valuable building blocks with high enantioselectivity. Moreover, this mild system allows for site-selective protection of optically pure syn-1,3-diols in excellent regioselectivity.

The extent of intramolecularhydrogenbonding, occurring in dilute CCl4 solutions, of members of the series (n = 2–5) HO.(CH2)n.OH and MeO.(CH2)n.OH has been determined. The results permit the interpretation of the patterns of hydrogenbonding in the three monomethyl ethers of butane-1,2,4-triol and in 1,4-dimethoxybutan-2-ol. In these compounds, where hydrogenbonding allows the formation of rings

Reduction of keto esters is a valuable alternative to produce diols. Sodiumborohydride/MeOH system at room temperature and short reaction time efficiently reduced α, β, γ, and δ-keto esters having α-keto esters as the most reactive. The ester functionality was reduced effectively due to the presence of oxo group that somehow facilitates the formation of ring intermediate. As expected, the chemoselective
