Intramolecularcycloadditions of the azomethine ylides bearing a carbonyl-activated olefinic moiety, generated from α-amino acids or esters and 5-oxo-6-heptenals or 4-oxo-5-hexenals, produce the stereoselective internal cycloadducts either to olefin or carbonyl dipolarophilic function with normal or inverse regioselectivity, depending upon the types of ylides as well as the intervening chain length

8-alkadienyl esters upon reaction with triphenylphosphinecopper hydride hexamer stereoselectively yields substitutedcyclohexanones having a cis relationship of carbon side chains at C2 and C3. This cyclohexanone construction is particularly useful for preparing 4-alkoxy- or 4-siloxy-2,3-disubstituted cyclohexanones, in which instance stereoselection is > or = 20:1.
