The title spirocarbopeptoid, C 11 H 13 N 2 O 5 , was prepared from l-fucose in a sequence that gave this and another anomer. The crystal structure determination removes ambiguities in the synthetic sequence.
The condensation of (1 R,2S) or (lS,2S)-N,N'-dimethyI-l-phenylpropane-l 2-diamines with aldehydes gives respectively two diastereorneric 2-alkyl-l,3,4-trimethyI-S-phen limidazolidines. At thermodynamical equilibrium the major isomer in the erythro series is this one where t f ! e substituents at pos
