The reaction of acetylacetone with α,β-enones in the presence of potassium carbonate affords 6-acetylcyclohex-2-enones. The assembly of two acetoacetate and one alkanal molecules gives 3,5-dialkylcyclohex-2-enones. Facile one-pot procedures for these reactions were developed.
Recyclization of 1,4-dihydropyridine derivatives in acidic medium

, p. 41 - 49 (2007/10/03)
The recyclization of 1,4-dihydropyridines in aqueous-alcoholic hydrochloric acid medium proceeds with cleavage of a C-N bond and pyridine ring opening. Cyclohexenone derivatives are formed as a result of the subsequent intramolecular crotonic condensation of the acyclic intermediate. The leaving carbonyl substituents depart simultaneously with recyclization, depending on the acidity of the reaction medium.
Regio- and Stereoselectivity of the Lactone Formation via Hydrolysis of the PO-Olefination Products of α,β-Epoxycyclohexanones

PO-Olefination of the diastereomeric pulegone oxides 1 and 2 with 9a leads to (E,Z) esters, 1 affording mainly (E)-3, and 2 predominantly (Z)-4. (Z)-4 hydrolyzes to give a mixture of γ- and δ-lactones 6-8; whereas (Z)-3 yields stereoselectively the δ-lactone 5. - The epoxy ketone 12 reacts with 9b to give the (E,Z) ester 13. (Z)-13 stereoselectively yields the γ-lactone 14.
