Diastereoselective pictet-spengler reactions of L-(boc)prolinal: a biomimetic synthesis of eudistomins H and I, and woodinine
摘要:
The carbon skeleton present in eudistomins H, I and in woodinine may be envisioned to be biosynthetically derived from tryptamine and L-prolinal by a Pictet-Spengler type reaction. The diastereoselectivity (> 5:1) of this reaction, and the elaboration of the Pictet-Spengler products into the title compounds is described. The absolute stereochemistry of (-) woodinine is thereby established.
