摘要

We wish to report herein a highly convergent approach to N b -desmethyl-meso-chimonanthine (3), the structurally simplest member of this class of alkaloid, which can provide access to more complex desymmetrised pyrrolidinoindoline alkaloids. The key step of the sequence is a diastereoselective tandem [4 + 2]-cycloaddition–cyclisation, inspired by the elegant synthesis of (±)-perophoramidine achieved by Fuchs and Funk. 14 We envisaged that this reaction could be applied in the ...
