Regio- and enantioselective cyclization of epoxy alcohols catalyzed by a [Co(III)(salen)] complex

The intramolecular cyclization of epoxy alcohols was catalyzed with excellent regio- and enantiocontrol by a [Co(III)(salen)] complex. High endo selectivity was observed for the enantioselective cyclization of terminal epoxy alcohols [Eq. (a)], while the reaction of meso substrates produced novel cyclic and bicyclic ethers in good yields and high enatiopurity. TBME = tert-butyl methyl ether.
Synthesis of Simple Oxetanes Carrying Reactive 2-Substituents

Ring-expansion of substituted epoxides using dimethyloxosulphonium methylide provides a convenient route to oxetanes carrying reactive 2-substituents that are capable of further modification.
TRANSPOSITION DES OXIRANNES-ETHANOLS PAR L'INTERMEDIAIRE D'ALCOXYETAINS. INFLUENCE DE LA CONFIGURATION DE L'OXIRANNE

The transposition of oxirane-ethanols, through alkoxytin compounds, into oxetane-2-methanols and/or oxolan-3-ols (tetrahydrofuran-3-ols) is dependent upon the oxirane configuration.Cis configuration is more suitable for the formation of the smallest ring.Steric hindrance is not sufficient enough to explain the results.
