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
摘要 从基于d-甘露醇的d-甘油醛丙酮化物转化为受保护的泛酸中间体,然后环化或与β-氨基酯形成酰胺键,已经开发了泛酸内酯和泛酸对映体的有效合成途径。然后进行适当的脱保护。 从基于d-甘露醇的d-甘油醛丙酮化物转化为受保护的泛酸中间体,然后环化或与β-氨基酯形成酰胺键,已经开发了泛酸内酯和泛酸对映体的有效合成途径。然后进行适当的脱保护。
