    通过动态气相热异构化(DGPTI)将多烷基苯基丙醇酸酯转化为多烷基环庚基[b]呋喃-2(2H)-酮,可以轻松制备多烷基化偶氮烯。后者与烯醇醚或烯胺发生热反应,生成相应的偶氮烯。烯胺可由相应的酰胺类物质就地生成,尤其是在由于烯胺的高反应性而难以获得纯烯胺的情况下。

However, heating of mixtures 1a/1b or 1a/1c results in the formation of crossed azulenes, namely 4,6,8-trimethyl-2-(2,3,4,5,6-pentamethylphenyl)azulene (4ba) and 2-(2,3,4,5,6-pentamethylphenyl)azulene (4ca), respectively (cf.

    A new method for the smooth and highly efficient preparation of polyalkylated aryl propiolates has been developed. It is based on the formation of the corresponding aryl carbonochloridates (cf. Scheme 1 and Table 1) that react with sodium (or lithium) propiolate in THF at 25 – 65°, with intermediate generation of the mixed anhydrides of the arylcarbonic acids and prop-2-ynoic acid, which then decompose

    Polyalkylated azulenes can easily be prepared from polyalkylphenyl propiolates which are transformed by dynamic gas phase thermo-isomerization (DGPTI) into polyalkylcyclohepta[b]furan-2(2H)-ones. The latter react thermally with enol ethers or enamines to the corresponding azulenes. The enamines may be generated in situ from corresponding aminals, especially, in cases where it is difficult to obtain the pure enamines due to their high reactivity.
