The first total synthesis of benzopyranobenzazepine alkaloid (±)- clavizepine (1) has been achieved by using the Bradsher cyclization of the keto ester 16 (leading to 18) and the Pummerer-type cyclization of the sulfoxide 25 (leading to 26) as the key ste

Triethyl 1,3-bis(3,4-dimethoxyphenyl)propane-1,2,2-tricarboxylate was synthesized by the alkylation of the lithium enolate of ethyl homoveratrate with α-bromo(3,4-dimethoxybenzyl)malonic ester.It was converted by intramolecular acylation, catalyzed by BF3
