SYNTHESIS OF (+/-)- AND (-)-CIS-TRIKENTRIN A, (+/-)- AND (-)-TRANS-TRIKENTRIN A, (+/-)-CIS-TRIKENTRIN B, (+/-)-TRANS-TRIKENTRIN B, AND (+/-)-ISO-TRANS-TRIKENTRIN B

Synthesis of the titled indole alkaloids from a marine source was accomplished according to the general scheme in Chart 1.The key steps were preparation of suitably substituted β-hydroxyl carbonyl compounds (8b) from 7b, and the subsequent indole cyclizat

DETERMINATION OF THE ABSOLUTE STRUCTURES OF CIS-TRIKENTRIN A AND TRANS-TRIKENTRIN A BY SYNTHESIS OF THEIR ENANTIOMERS

(-)-cis-Trikentrin A (20) and (-)-trans-trikentrin A (21) were synthesized from (R)-3-methyladipic acid by way of pyrrole derivatives 14, 15, and 17, establishing the absolute structure of the natural cis- and trans-trikentrins A to be 1 and 2.
