The invention relates to new heterocyclic compounds containing a protected C-acetyl group. More particulary, the invention concerns new compounds of the formula (VI) ##STR1## wherein R.sup.1 is hydrogen or a group suitable for a temporary protection or amides, X is hydroxyl, halogen, cyano or an --O--SO.sub.2 --R.sup.2 group, in which R.sup.2 is lower alkyl or aryl, Y.sup.1 and Y.sup.2 together form a group suitable for a temporary protection of a keto group. The new compounds possess anaphylactic properties and are valuable intermediates of thienamycin synthesis. Their preparation and the new intermediates obtained during their preparation are also within the scope of the invention.
该发明涉及含有保护的C-乙酰基团的新杂环化合物。更具体地,该发明涉及具有以下结构的新化合物(VI)##STR1##其中R.sup.1是氢或适用于临时保护或酰胺的基团,X是羟基、卤素、氰基或--O--SO.sub.2--R.sup.2基团,其中R.sup.2是较低的烷基或芳基,Y.sup.1和Y.sup.2共同形成适用于酮基的临时保护基团。这些新化合物具有抗过敏性质,并且是噻氨霉素合成的有价值的中间体。它们的制备以及在制备过程中获得的新中间体也属于该发明的范围内。
