The synthesis of cepharadione-B and 2-demethoxy analogues is described. Starting from fluorenones, ring C was formed by cyclization of (biphenyl-2-yl)acetyl morpholines under Bischler-Napieralsky conditions. The photochemistry of chloroacetamides was used to form ring B. The cytotoxicity of these compounds on several tumor cell lines was evaluated.
描述了头孢拉酮-B和2-脱甲氧基类似物的合成。由芴酮开始,在Bischler-Napieralsky条件下,环化(联苯-2-基)乙酰基吗啉形成环C。氯乙酰胺的光化学用于形成环B。评估了这些化合物对几种肿瘤细胞系的细胞毒性。
