been developed starting from d-mannitol-based d-glyceraldehyde acetonide through its conversion into a protected pantoic acid intermediate followed by either cyclization or amide bond formation with a β-amino ester, and subsequent appropriate deprotection. Efficient synthetic routes to both the enantiomers of pantolactone and pantothenic acid have been developed starting from d-mannitol-based d-glyceraldehyde
