Biomimetic Synthesis of Thiaplidiaquinones A and B
摘要:
A biomimetic synthesis of the biologically active ascidian metabolites thiaplidiaquinones A and B is described. Reaction of geranylbenzoquinone with Et3N in CH2Cl2 yielded two isomeric quinones, comprising the benzo[c]chromene-7,10-dione core of the natural products. Subsequent reaction with hypotaurine yielded the title compounds and their dioxothiazino regioisomers.

thiaplidiaquinones A and B and their respective non-natural dioxothiazine regioisomers have been shown to inhibit mammalian and protozoal farnesyltransferase (FTase) with the regioisomers exhibiting activity in the nanomolar range. In order to explore the structure-activityrelationship (SAR) of this class of marine natural products, analogues of thiaplidiaquinones A and B and their regioisomers were
