Novel 4-phenyl-4-substituted-5-oxo-7-aryl-heptanoic acids are prefaced by either of two synthetic processes. The first method involves the reaction of a 4-phenyl-4-substituted-5-oxo-hexanoic acid with an arylcarboxyaldehyde. The second method involves reaction of an arylcarboxaldehyde with an appropriate ketone, treatment of the product with an acrylic acid ester, followed by hydrolysis of the resulting ester. The compounds of the invention are prostaglandin antagonists and are particularly useful as topical anti-inflammatory agents.
小说4-苯基-4-取代-5-酮-7-芳基庚酸可以通过两种合成过程中的任何一种进行引言。第一种方法涉及将4-苯基-4-取代-5-酮己酸与芳基羧醛反应。第二种方法涉及芳基羧醛与适当的酮反应,处理产物与丙烯酸酯,然后水解生成的酯。本发明的化合物是前列腺素拮抗剂,特别适用于作为局部抗炎药物。
