Cover Feature: Synthesis of Pyrrolo[2,1‐a]isoquinoline Class of Natural Product Crispine A (Eur. J. Org. Chem. 35/2021)

Abstract

The Cover Feature shows naturally occurring (2S,3S)- and (2S,3R)-tetrahydro-3-hydroxy-5-oxo-2,3-furan dicarboxylic acid bearing, chemically amenable functional groups that are an ideal choice for the enantiopure synthesis of the (−)- and (+)-Crispine A, respectively. The diastereomeric natural products are conveniently converted to desirable enantiomers of Crispine A through the chiral pool strategy. This exciting and efficient strategy is one of the well-explored trends in synthetic organic chemistry, especially regarding molecules procured from tropical plant material (Nature) and serves as key step in the enantiopure synthesis of small-molecule natural products.
