Bulletin of the Agricultural Chemical Society of Japan, 1959 α-Exo-unsaturated-γ-butyrolactones were prepared. Reduction of α-benzylidene succinic acid esters with lithium aluminum hydride afford 2-benzylidene-1,4-butanediols. Manganese dioxide oxidation of glycols followed by silver oxide oxidation and lactonization afford α-benzylidene-γ-butyrolactones. Thus α-benzylidene-, α-anisylidene-, α-veratrylidene-, α-(

Syntheses of Unsaturated Lactones
Agricultural and Biological Chemistry, 1969 6-Pentyl-α-pyrone, 6-propyl-α-pyrone and 4-decenoic acid-δ-lactone were prepared, and the nature of their flavors was investigated. Unsaturated lactones having the best flavorous nature as a butter or butter cake flavor among the lactones having double bond at various site, were 2-ene-δ-lactones which have a double bond at the α-position of the lactone

Microbial Reduction of Ketopantoyl Lactone to Pantoyl Lactone [PDF]
Applied Microbiology, 1974 The results of a microbial survey study have shown that the ability to reduce added ketopantoic acid (or ketopantoyl lactone) and accumulate pantoic acid (or pantoyl lactone) in the growth medium is widespread among diverse fungi. The reductions generally proceeded with less than full stereoselectivity.

Antimicrobial Activity of Lactones
Antibiotics, 2022 The development of bacterial resistance to antibiotics and the consequent lack of effective therapy is one of the biggest problems in modern medicine. A consequence of these processes is an urgent need to continuously design and develop novel antimicrobial agents. Among the compounds showing antimicrobial potential, lactones are a group to explore.
