Intramolecular cyclodehydration of (4S)-(+)-4-carboxyethyl-4-(pyrrol-1-yl)butanal as the key step in the formal synthesis of (S)-(−)-Myrmicarin 217
摘要:
(S)-(-)-Myrmicarin 217, a tricyclic alkaloid recently discovered in the poison glands of Myrmicaria ants, has been formally synthesized. The intramolecular cyclodehydration of 4-carboxyethyl-4-(pyrrol-1-yl)butanal is the key step in the construction of the required six-membered ring. (C) 2003 Elsevier Science Ltd. All rights reserved.
