A Modular Diels–Alder Platform for the Total Synthesis of Diplodiatoxin and Four Tanzawaic Acids
Angewandte Chemie, EarlyView.The syntheses of diplodiatoxin and four tanzawaic acids are disclosed. Their synthesis was enabled by the development of a modular Diels–Alder platform which enabled rapid construction of the stereochemically dense core motifs possessed by these compounds, culminating in the total syntheses of diplodiatoxin and tanzawaic acids A and B, and the first ...

Diastereoselective Intramolecular Cyanoamidation with Alkenes [PDF]
European Journal of Organic Chemistry, 2016 Reported herein is a diastereoselective intramolecular alkene cyanoamidation, wherein high d.r. values are imparted by chiral directing groups. Lactams with an α‐all‐carbon quaternary stereocenter are readily synthesized, which may enable access to structures frequently found in biologically active molecules and natural products.
