5-methoxy-1H-naphtho[2,1,8-mna]xanthen-1-one (1) and 5-methoxy-3H-naphtho[2,1,8-mna]xanthen-3-one (musafluorone 2), a pair of positional isomers isolated from Wachendorfia thyrsiflora and Musa acuminata, were synthesized in six steps in an overall yield of 53 % and 59 % starting from the corresponding methoxyphenalenones and employing an acid mediated cyclocondensation strategy. Preliminary assays
5-甲氧基-1 H-萘[2,1,8 - mna ]黄原-1-酮(1)和5-甲氧基-3 H-萘[2,1,8 - mna ]黄原-3-酮(Musafluorne 2),从相应的甲氧基对苯二酚开始,采用酸介导的环缩合策略,分六步合成了一对从Wachendorfia thyrsiflora和Mus acuminata分离出的位置异构体,总收率分别为53%和59%。初步测定证明了化合物1和2嵌入DNA的能力。
