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.
本发明涉及一种含有保护的C-乙酰基团的新杂环化合物。更具体地,本发明涉及公式(VI)的新化合物:##STR1## 其中R1是氢或适合于临时保护或酰胺的基团,X是羟基、卤素、氰基或-O-SO2-R2基团,其中R2是较低的烷基或芳基,Y1和Y2一起形成适合于酮基临时保护的基团。这些新化合物具有过敏性质,是噻呋霉素合成的有价值的中间体。它们的制备以及制备过程中获得的新中间体也在本发明的范围内。
