โœฆ Synopsis

Imidazolidine-2,4-dione was chemoselectively N-alkylated at the imidic NH with several 2-(3,4-dihydro-1-naphthalenyl)ethyl-4-methylphenylsulphonates to give the corresponding imides for the first time which on selective reduction at one of the carbonyl groups followed by cyclization in PPA gave the corresponding title compounds.

The recently isolated marine natural product pseudoceratidine (1) has been synthesized from 2-trichloroacetylpyrrole. Bromination in the 4-and 5-position followed by nucleophilic displacement of the trichloromethyl group with spermidine gave 1 in 79 g yield. The procedure is general and can easily b
