  • Asymmetric Total Synthesis of the Indole Diterpene Alkaloid Paspaline
    作者:Robert J. Sharpe、Jeffrey S. Johnson
    DOI:10.1021/acs.joc.5b01844
    日期:2015.10.2
    An enantioselective synthesis of the indole diterpenoid natural product paspaline is disclosed. Critical to this approach was the implementation of stereoselective desymmetrization reactions to assemble key stereocenters of the molecule. The design and execution of these tactics are described in detail, and a thorough analysis of observed outcomes is presented, ultimately providing the title compound

  • A Global and Local Desymmetrization Approach to the Synthesis of Steroidal Alkaloids: Stereocontrolled Total Synthesis of Paspaline
    作者:Robert J. Sharpe、Jeffrey S. Johnson
    DOI:10.1021/jacs.5b02631
    日期:2015.4.22
    A stereocontrolled total synthesis of the indole diterpenoid natural product paspaline is described. Key steps include a highly diastereoselective enzymatic desymmetrization, substrate-directed epoxidation, Ireland-Claisen rearrangement, and diastereotopic group selective C-H acetoxylation to assemble the target with excellent stereofidelity. The route and results described herein outline complementary

  • Nodulisporic acid E biosynthesis: <i>in vivo</i> characterisation of NodD1, an indole-diterpene prenyltransferase that acts on an emindole SB derived indole-diterpene scaffold
    作者:Kyle C. Van de Bittner、Rosannah C. Cameron、Leyla Y. Bustamante、Rudranuj Bundela、Sarah A. Kessans、Jan Vorster、Matthew J. Nicholson、Emily J. Parker
    DOI:10.1039/c9md00143c
    日期:——
    Prenylation of aromatic compounds is a key tailoring reaction in biosynthesis of bioactive indole-diterpenes. Here, we identify NodD1 as the enzyme responsible for the bisprenylation of nodulisporic acid F. This prenyltransferase showed a preference for its natural indole-diterpene substrate whereas other related enzymes were not able to catalyse this conversion.

  • Indole diterpene synthetic studies. 2. First-generation total synthesis of (-)-paspaline

  • Total Synthesis of Paspaline A and Emindole PB Enabled by Computational Augmentation of a Transform-Guided Retrosynthetic Strategy
    作者:Daria E. Kim、Joshua E. Zweig、Timothy R. Newhouse
    DOI:10.1021/jacs.8b13127
    日期:2019.1.30
    We report the total syntheses of two indole diterpenoid natural products, paspaline A and emindole PB. Paspaline A is synthesized in a 9-step sequence from commercially available materials. The first total synthesis of emindole PB is accomplished in 13 steps and confirms a previously ambiguous structural assignment. Density functional theory calculations are utilized to interrogate the key carbocationic rearrangement in a predictive capacity to aid in the selection of the most favorable precursor substrate. This work highlights how retro-synthetic design can be augmented with quantum chemical calculations to reveal energetically feasible synthetic disconnections, minimizing time-consuming and expensive empirical evaluation.
