✦ Synopsis

Sumnary: Optically active carnosadine , a new cyclopropyl amino acid from red alga Gratebupia oarnosa, was synthesized and its absolute structure was determined. In a previous paper, we reported an isolation of a new amino acid carnosadine (l), lamino-Z-guanidinomethylcyclopropane-1-carboxylic acid, from marine red alga GrateZoupia o-sa.l) By comparison of the 'H-NMR spectrum of carnosadine2) with those of l-amino-Z-Bz-Gly -!-w iii ) MeO,C
