The levo-lactonase gene of Fusarium proliferatum ECU2002 (EC3.1.1.25) was cloned and expressed in Escherichia coli JM109 (DE3) for biocatalytic resolution of industrially important chiral lactones, including DL-pantoyl lactone which was a key precursor to calcium D-pantothenate. By increasing the biomass

We developed an enzymatic resolution system for DL-pantoyl lactone that uses immobilized mycelia of Fusarium oxysporum, which produce a lactone-hydrolyzing enzyme (lactonase). The lactonase catalyzes the stereospecific hydrolysis of D-pantoyl lactone. One hundred eighty repeated batch reactions (total reaction time
A gas chromatographic procedure is described for quantitative estimation of alpha-hydroxy-beta 1 beta-dimethyl-gamma-butyrolactone (pantolactone). The chromatography was carried out using "LHM-8MD" apparatus equipped with a flame ionization detector. Columns with chromaton N-AW modified by 5% silicone XE-60 were used, helium

An efficient synthesis of potent molluscicidal agent cyanolide A, a glycosidic 16-membered macrolide, starting from D-(-)-pantolactone is reported. Highly stereoselective aldol, oxa-Michael addition, and Yamaguchi macrolactonization are the key steps in the present synthesis.
