Reactivity of alicyclic 1,5,9-triketones toward five-, six-, and seven-membered rings in acidic medium. Stereochemistry of intramolecular cyclization products

[Figure not available: see fulltext.] Among nine alicyclic 1,5,9-triketones with differently fused 5-, 6-, and 7-membered rings in the molecule, existing as mixtures of 3–6 diastereomers, only those containing at least two 6-membered rings were capable of

Methods of synthesis of alicyclic 1,5,9-triketones. Reaction of transaminomethylation

Alicyclic 1,5,9-triketones with various combination of 5-, 6-, 7-membereded cycles in the molecule were obtained by methods of diketone condensation, Michael reaction, and proceeding from Mannich mono- and bisbases and cycloalkanones. The latter method wa

Condensations of Aldehydes and Ketones. XXVII. Alkaline Condensation of 2-(2-Oxocyclopentylmethyl)- and 2-(2-Oxocyclohexylmethyl)cycloheptanones with Aromatic Aldehydes

Alkaline condensation of aromatic aldehydes with 2-(2-oxocyclopentylmethyl)cycloheptanones yields substituted perhydropyran-3-spiro-1′-cyclopentan-2′-ones. 2-(2-Oxocyclohexylmethyl)cycloheptanone reacts with aromatic aldehydes with formation of noncrystallizable mixtures of arylmethylene derivatives. The latter are converted into corresponding arylmethylenetetrahydrochromenylium salts by the action of an acetic acid-perchloric acid mixture.

REGIODIRECTION OF THE FORMATION OF KETOAMIDES IN THE THERMOLYSIS OF DERIVATIVES OF 2,6-EPIDIOXYPIPERIDINE

Thermolysis of a series of unsymmetrically substituted bi- and tricyclic derivatives of 2,6-epidioxypiperidine leads to the predominant formation of only one of the possible ketoamides; this is probably associated with the synchronous course of the reacti
