The total synthesis of the polyalkoxylated alkaloids piperolactam C, goniopedaline and stigmalactam by combinatorial metalation/cyclization strategies has been achieved. The synthetic route involved the preliminary construction of the polyalkoxylated isoindolinone template by Parham's technique. Benzylic lactam deprotonation allowed connection of a hydroxybenzyl appendage, and the synthesis of the target natural products was completed by subsequent E1cB elimination, radical cyclization and final deprotection.

Oxidative coupling of 2,2',4,4'-tetramethoxystilbene-3,3'-diol 51 gave a 51percent yield of 1,3,6,8-tetramethoxyphenanthrene-2,7-quinone 52, the first isolated example of a quinone of this type.Similar oxidation of the corresponding diphenylethane 55 gave
