A direct synthesis of neocryptolepine and isocryptolepine
摘要:
A formal synthesis of indolequinoline alkaloid neocryptolepine and isocryptolepine is described which employed a common intermediate and used an intramolecular Wittig reaction followed by regioselective methylation in excellent yield. (C) 2010 Elsevier Ltd. All rights reserved.
A facile synthesis of various functionalized 3-substituted quinolin-2(1H)-ones through Ag(I) nitrate-catalyzed cyclization of o-alkynylisocyanobenzenes is described. The reaction allows rapid and convenient access to 3-substituted quinolin-2(1H)-one scaffolds in moderate to good yields.
