Photo-Cycloaddition of 3-Methoxycyclohexenone and 3-Aminocyclohexenone to Ethoxyethylene: Stereochemistry of the Cycloadducts

Irradiation of a methanolic solution of 3-methoxycyclohexenone and ethoxyethylene with 254 nm light gave four stereoisomeric head-to-tail cycloadducts in the ratios indicated in Fig. 3.The structure and stereochemistry of all the isomers were determined by chemical correlations and spectroscopic means, respectively.The time-course product analysis suggested that, in this reaction, the exo and endo oriented ?-complexes are equally formed, both give the cycloadducts with a slight preference for antara-selectivity.The analogous cycloadduct of 3-aminocyclohexenone to ethoxyethylene decomposed into 2-ethoxycyclooctane-1,5-dione on silica gel chromatography.Keywords - photo-cycloaddition; stereochemistry; 3-methoxycyclohexanone; 3-aminocyclohexenone; acyclic olefin; 2+2 adduct; bicyclooctanone; cyclooctanedione; 2D NMR; time-course product analysis
