    摘要: Novel blood sugar-lowering dihydropyridinelactones of the formula ##STR1## in which R represents halogen, C.sub.1 -C.sub.10 -alkyl, C.sub.1 -C.sub.10 -alkoxy, C.sub.1 -C.sub.10 -alkylthio, C.sub.1 -C.sub.10 -alkylsulphinyl, C.sub.1 -C.sub.10 -alkylsulphonyl, cyano, C.sub.1 -C.sub.6 - mono- or polyfluoroalkyl, C.sub.1 -C.sub.6 -mono- or polyfluoroalkoxy or nitro,R.sup.1 represents hydrogen, halogen or C.sub.1 -C.sub.10 -alkyl or C.sub.1 -C.sub.10 -alkoxy,R.sup.2 represents a C.sub.1 -C.sub.20 hydrocarbon radical which can optionally be interrupted or substituted,R.sup.3 represents hydrogen NH.sub.2, CHO, CN or a C.sub.1 -C.sub.6 hydrocarbon radical which can be interrupted in the chain, andR.sup.4 represents a C.sub.1 -C.sub.10 -alkyl or C.sub.2 -C.sub.10 -alkenyl radical which can optionally be interrupted or substituted with the proviso that R is not CF.sub.3 if R.sup.2 represents C.sub.2 H.sub.5.
