Five 2-aroyl-3-aryl-5H-furo[3,2-g]chromene derivatives have been synthesized, and their structures were characterized by IR, NMR, ESI-MS and elemental analysis. The crystal structure for 2-benzoyl-3-(4-methoxyphenyl)-6,7-dihydro-5H-furo[3,2-g]chromene has been determined by single-crystal X-ray diffraction. X-ray analysis reveals that the pyran ring adopts a half-chair conformation, while the fused
合成了5个2-芳酰基-3-芳基-5H-呋喃[3,2-g]色烯衍生物,并通过IR、NMR、ESI-MS和元素分析对其结构进行了表征。2-苯甲酰基-3-(4-甲氧基苯基)-6,7-二氢-5H-呋喃[3,2-g]色烯的晶体结构已通过单晶X射线衍射确定。X射线分析表明,吡喃环采用半椅式构象,而稠合的呋喃[3,2-g]色烯环大致共面,略有变形。初步药理试验表明,所有目标化合物均对 U2OS-EGFP-4F12G 细胞系表现出细胞毒性。
