description | Madangamines are a group of bioactive marine sponge alkaloids, embodying an unprecedented diazapentacyclic skeletal type. The enantioselective total synthesis of madangamine D has been accomplished, and represents the first total synthesis of an alkaloid of the madangamine group. It involves the stereoselective construction of the diazatricyclic ABC core using a phenylglycinol‐derived lactam as the starting enantiomeric scaffold and the subsequent assembly of the peripheral macrocyclic rings. The synthesis provides, for the first time, a pure sample of madangamine D and confirms the absolute configuration of this alkaloid family.
Ein Alkaloid der Madangamin‐Familie konnte erstmals synthetisiert werden. Ausgehend von einem Lactam auf Phenylglycinolbasis wurden nacheinander die Sechsringe C und A von (+)‐Madangamin D aufgebaut, und die so erhaltenen funktionalisierten ABC‐Diazatricyclen wurden dann mit den äußeren Makrocyclen D und E versehen. Ts=4‐Toluolsulfonyl. |
