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
