3, 4-Dihydroisoquinolines and 3, 4-dihydro-β-carbolines react with trimethylsilyl trifluoromethanesulphonate to form complexes that react readily with the lithio derivatives of 3-cyano-4-methylpyridines; the method has been applied to the synthesis of the Alangium alkaloids,(±)-alangimaridine and alangimarine.
