The spermidine alkaloids (+)-(2S)-dihydromyricoidine (5) and (+)-(2S)-myricoidine (4) were synthesized under asymmetric conditions. The synthetic compounds 4 and 5 were found to have positive [α] d 21 values in both cases, which agrees with those of

An asymmetric synthesis of the spermidine alkaloid (−)-(2R)-dihydromyricoidine (5) was performed by employing two ring-enlargement reactions. The chiral center was introduced by a diastereoselective Michael addition of perhydropyridazine (7) to the
