The route begins with the conversion of ethyl 3,3-diethoxy-2,2-dimethylpropanoate directly to the methyl ketone, which was then transformed into to the corresponding vinyl triflate in essentially perfect yield. This was then Kumada coupled to ClMgCH2SiMe3 to form the allyl silane later required for the key Sakurai reaction.

S.PY - 1974Y1 - 1974N2 - The reaction of 3,4‐dihydro‐6,7‐dimethoxyisoquinoline hydrochloride on ethyl vinyl ketone yields two cis and trans benzo[a quinolizinone isomers in variable proportions depending on the pH of the reacting medium.

In this reaction the enolate of diethyl malonate adds to the carbon of methyl vinyl ketone.

to prepare polyketones (eq 4)., Carboannulations may be effected by sequential Michael reactions or a combination of Michael and aldol reactions. However, attempts to generate the tricyclo[,8]undecane ring system by three sequential Michael reactions between divinyl ketone and cyclohexenone enolate failed. The desired assembly was eventually achieved by an initial Diels-Alder cycloaddition, followed by a Michael reaction (eq 5), and provided the foundation of a synthesis of seychellene. A similar case, employing acid catalysis in the cycloaddition step, was interpreted as a threefold sequence of Michael reactions.Unsaturated ketones are excellent dienophiles.

Preparation of Anhydrous Methyl Vinyl Ketone and …

An interesting study of sequential Diels-Alder reactions of conjugated tetraenes with dialkenyl ketones to give tricyclic products has been reported. Dimethylhydrazone derivatives of divinyl ketone react with strong dienophiles to give heterocyclic products.Addition of carbon radicals to divinyl ketone may yield useful polyfunctional products (eq 6). 1,2-Carbonyl addition reactions are best accomplished with precursors (Table 1).
