Novel unsaturated ethers were synthesised in good yields starting from sucrose,using a two-step mild and efficient procedure based on the Gassman method, which consists in forming a vinyl group by the elimination of ethanol from mixed acetals with trimethylsilyl trifluoromethanesulfonate in the presence of alkyl amines. Mixed acetals are readily obtained(More)
Improved fertilizer recommendations based on experimental data are required to increase organic crop yields. With this aim, a field organic crop rotation with lettuce (Lactuca sativa L.) followed by a cover crop of hairy vetch (Vicia villosa Roth) and rye (Secale cereale L.), and by organic Swiss chard (Beta vulgaris L. var. cicla L.), was arranged as a(More)
