Chloroacetamide Photocyclization. Synthesis of 20-Deethylcatharanthine

20-Deethylcatharanthine, a potential precursor of vinblastine-type dimeric indole alkaloids, has been synthesized in ten steps from 1-benzenesulfonylindole.The Synthesis features a Diels-Alder reaction between 1-carbethoxy-1,2-dihydropyridine and ethyl 2-
