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.
1,6-Anhydro-β-D-glucopyranose in organic synthesis: preparation of a fragment for the synthesis of rosaramycin

1,6-Anhydro-β-D-glucopyranose has been used as the starting material for a synthesis of ethyl (E)-4-C-allyl-2,3,4,6-tetradeoxy-5,7-O-isopropylidene-8-O-methanesulphonyl-2,6-di-C-methyl-D-gulooct-2-enonate, which represents a synthetic unit equivalent to C-2/9 of the macrolide antibiotic rosaramycin.The synthesis involved a minimum of chromatography, and the extremely high level of regiochemical and stereochemical control was achieved by the use of epoxides at crucial C-C-bond-forming steps.A method was also developed, using tosylmethyl isocyanide, which converted a carbohydrate 6-aldehyde (19) directly into the corresponding homologated methyl ether.
