1,3-Asymmetric Induction in the Reaction of Organometallics to β-Hydroxy Ketones and β-Silyloxy Ketones

High level of 1,3-asymmetric induction was realized in the reaction between β-hydroxy ketones and triisopropoxytitanium reagents to give anti-1,3-diols possessing tertiary alcohols.To the contrary, syn-1,3-diols were obtained by the addition reaction of organometallics to β-t-butyldimethylsilyloxy ketones.

SYNTHESIS AND DECOMPOSITION OF E- AND Z-3,3,5-TRISUBSTITUTED 1,2-DIOXOLANES.

The reactions of a number of ozonides and olefins in the presence of boron trifluoride-diethyl ether gave the corresponding mixtures of (E)- and (Z)-1,2-dioxolanes in 12-70% yield. The decomposition of the E-Z isomeric 1,2-dioxolanes 3a-c was undertaken under a variety of conditions, i. e. , thermal, TiCl//4-mediated, FeSO//4-catalyzed, and LiAlH//4-mediated decompositions.
