indoloberbine ring skeletons is reported. Treatment of heterocyclicbases such as isoquinolines, phthalazines, and ellipticine with 2-chloromethylbenzoyl chloride and trimethylsilyl cyanide gave the corresponding Reissert compounds. Treatment of these Reissert compounds with sodium hydride resulted in intramolecular cyclization with loss of hydrogencyanide.

A new total synthesis of the berbine alkaloid ring system has been achieved. Palladium catalyzed insertion of carbon monoxide into the 1 - (2 - bromobenzyl) - substituted - 1,2,3,4 - tetrahydroisoquinolines (1a–1d) by the use of catalytic amounts of palladium diacetate and triphenylphosphine in the presence of tri-n-butylamine afforded the berbin-8-ones (2a–2d) which, on reduction with lithium aluminium
