Indole Diterpene Synthetic Studies. 5. Development of a Unified Synthetic Strategy; a Stereocontrolled, Second-Generation Synthesis of (-)-Paspaline

We record here a full account of a highly stereocontrolled, second-generation synthesis of (-)-paspaline (1).The synthesis proceeded via an initial nine-step conversion of (+)-Wieland-Miescher ketone to tricyclic cyclopentanone 5, an intermediate that we

Indole-Diterpene Synthetic Studies. 3. A Unified Synthetic Strategy For The Simple Indole Tremorgens

In this letter we record an efficient synthesis of tricyclic ketone 5, a common advanced intermediate for construction of the simple indole-diterpene tremorgenic alkaloids.
