1. The de novo synthesis of racemic CM1 on the basis of synthetic route of clausenamide was accomplished by starting with N-p-methoxylbenzyl-β-hydroxyl-β-phenylethylamine (1.1-3), through ester-amine exchanging with p-phenylglycidate, oxidation, intramolecular cyclization, debenzylation, reduction, and hydroxymethylation, The enantiomers of CM1 were prepared by resolution of the key intermediate--p-methoxylbenzyl-demethyl-clausenamidone (I.1-14) with N-phthalyl-L-alanine, the resulting diasteroisomers could be separated preceding by debenzylation.
