A one-pot transformation of some cyclic 1,3-dicarbonyls 1 with N-(isonicotinoyl)glycine 2 and one-carbon synthons in acetic anhydride to the corresponding N-substituted isonicotinamides (pyridine-4-carbox-amides) 7-9 containing a fused pyran-2-one ring is described. Compound 8 was further converted with some nitrogen-containing nucleophiles either to the corresponding quinoline-2,5-diones 10-11 or
一些环状1,3-二羰基1与甲一锅转化ñ - (异烟酰基)甘氨酸2在乙酸酐成相应的和一碳合成子Ñ取代isonicotinamides(吡啶-4-羧酰胺)7-9含有描述了稠合的吡喃-2-酮环。化合物8用一些含氮亲核试剂进一步转化为相应的喹啉-2,5-二酮10-11或5-水-偶氮苯并吡喃-2-酮14-15。在更苛刻的条件下,化合物8与肼5-肼基喹啉衍生物12或什至13。氢氰酸将化合物8转化为吡喃-[3,2- c ]氮杂系统16。1-氨基衍生物10重氮化可得到脱氨基产物11。
