5-(.alpha.-D-glucopyranosyloxymethyl)-furan-2-carboxaldehyde (GMF) is produced from isomaltulose by heating a solution of isomaltulose in a strongly polar aprotic solvent in the presence of an acidic ion-exchanger, either batchwise or by percolation of the solution through a column filled with the ion-exchanger. Novel derivatives of GMF of the formula (I) ##STR1## wherein R' is a hydrogen atom, an acyl group or an alkyl group and X represents --CH.sub.2 OH, --COOH, --C(H).dbd.NOH, --CN, --CH.sub.2 NHR" or --CH.dbd.CR"R'", where R" is a hydrogen atom, an acyl or aryl group or an alkyl group with up to 20 C atoms and R'" is a hydrogen atom, --NO.sub.2, --CN, --COOalkyl or acyl are described, and also their preparation and use for the preparation of surface-active compounds.
通过在强极性非质子溶剂中加热异麦芽糖溶液,并在酸性离子交换剂的存在下进行,可以生产5-(α-D-葡萄糖吡喃基氧甲基)-呋喃-2-甲醛(GMF)。可以通过分批或通过将溶液通过填有离子交换剂的柱进行渗透来制备GMF的新衍生物,其化学式为(I)其中R'是氢原子、酰基或烷基,X代表--CH2OH、--COOH、--C(H)═NOH、--CN、--CH2NHR"或--CH═CR"R'",其中R"是氢原子、酰基或芳基,或有多达20个碳原子的烷基,R'"是氢原子、--NO2、--CN、--COO烷基或酰基。还描述了它们的制备和用于制备表面活性化合物的用途。
