All plants synthesize pantothenate but its synthesis and regulation are not well understood. The aim of this work is to study the effect of exogenous supply of precursor compounds on pantothenate levels in leaves. Precursor compounds were supplied in solution

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.

A series of novel N,O-psiconucleosides has been prepared in both enantiomeric forms by resolution of an advanced racemic synthetic intermediate using (R)-N-phenylpantolactam as a chiral resolution agent. The absolute configuration of all of these compounds has been unequivocally established by

A pseudomonad was separated having a pantothenase that produced beta-alanine and pantoic acid. The pantothenase from an old strain, Pseudomonas fluorescens UK-1, was shown to produce beta-alanine and pantoyl lactone. The pantoic acid-producing pantothenase was characterized and compared with the
