Crispine A is a representative alkaloid bearing pyrrolo[2,1-a]isoquinoline to exhibit various biological activities. In this report, enantiodivergent synthesis of crispine A has been achieved, featuring a stereoselective 1,3-dipolar cycloaddition and an enzymatic kinetic resolution. The sequential process including cleavage of the N—O bond and cyclization proved to be effective and practical toward pyrrolo[2,1-a]isoquinoline in intriguing bioactive alkaloids. The capacity of enzymatic resolution dictated in this work is of great interest to accumulate the tetrahydroisoquinoline (THIQ)-fused pyrrolidine which is commonly embedded in various bioactive compounds.

Key words: chemoenzymatic synthesis, dipolar cycloaddition, enantiodivergent synthesis, kinetic resolution, nitrone
