Tricyclic systems generated by an asymmetric vinylogous aldol-oxa-Michael reaction of salicylaldehydes with senecialdehyde were further elaborated using a strategy developed by Tietze et al. to generate 4a-methyl tetrahydroxanthones.
由水杨醛与千里光醛进行不对称的维尼洛醇-氧杂迈克尔反应生成的三环系统,进一步采用Tietze等人开发的策略,合成了4a-聚甲基四羟基香豆素。
