1,6-anhydro-β-hexopyranose derivatives and their use as herbicides and plant growth regulators

Herbicidal and/or plant-growth regulatory compositions comprising, together with a carrier and/or surface-active agent, an effective amount of at least one herbicidal and/or plant growth regulatory active agent selected from compounds of formula (I) STR1 (in which R represents an optionally substituted aralkyl group, X represents an O--, N-- or S-linked organic group, an optionally substituted hydrocarbyl group, a halogen atom, a hydroxy, amino, alkoxyamino, nitro, cyano, azido, sulpho or phospho group, or together with the group R2e, X may represents a ketonic oxygen atom --O-- or a group of formula --CH2 O--; R1e represents a hydrogen atom or an optionally substituted hydrocarbyl group, or a formyl group; R2e represents a hydrogen atom, a hydroxy group or an optionally substituted hydrocarbyl or O-linked hydrocarbyl group, or, together with the group X, R2e may represent a ketonic oxygen atom --O-- or a group of formula --CH2 O--; R3a represents a hydrogen atom, a hydroxy group or an optionally substituted alkoxy, alkenyloxy, aralkoxy or C1-4 hydrocarbyl group; R3e represents a hydrogen atom, a hydroxy group or an optionally substituted hydrocarbyl or O-linked hydrocarbyl group; and R4e represents a hydrogen atom or an optionally substituted hydrocarbyl group) and enantiomers and salts thereof. Methods for preparing the compounds of formula (I) are described; the compositions are valuable as herbicides and/or plant-growth regulants, particularly for use with crops such as soya, rape, sugar-beet, cotton, wheat, maize and rice.

Regioselective De-O-benzylation with Lewis Acids

Simple and highly regioselective de-O-benzylations of poly-O-benzylated monosaccharides and polyols with Lewis acids (SnCl4 and TiCl4) were developed.Spectral studies on intermediates complexes showed that three appropriately situated metal chelating functional groups were necessary for the selective de-O-benzylation.
