A study was made of the condensation of bicyclic γ-lactone I with furylacrolein and furylpropionic aldehyde. Significant differences were observed in the reactivity of the aldols obtained, and in the stereochemical trend of their dehydration reactio

Reaction of (+)4-mesyloxymethylene-2-oxabicyclo[3.3.0]-6-octen-3-one with Ω-amino acids of different lengths gave (+)4-carbomethoxyalkylaminomethylene-2-oxabicyclo[3.3.0]-6-octen-3-ones. For the γ-aminobutyric ester, the corresponding aminomethylen

Derivatives of α-alkyl-, α-alkylidene-, and α-hydroxymethylene-2-oxabicyclo[3.3.0]-6-octen-3-one were obtained. The possibility of functional substitution of the bicyclic γ-lactones at the α position to the carbonyl group was thereby demonstrate
