摘要： 3-Hydroxy-3-substituted glutaric acid derivatives are prepared in two steps. An ester of a carboxylic acid is reacted with a 2alkenyl magnesium bromide and the resulting 4-substituted-4hydroxy-1,6-heptadiene is ozonized, then oxidized to form the 3hydroxy-3-substituted glutaric acid. These compounds have antiulcerogenic activity.
