The synthesis of indanones related to combretastatin A-4 via microwave-assisted Nazarov cyclization of chalcones
摘要:
A fast and efficient microwave-assisted synthesis of combretastatin A-4-like indationes has been developed. Microwave irradiation provides a useful alternative to traditional heating techniques to promote the TFA-catalyzed Nazarov cyclization of chalcones. (c) 2006 Elsevier Ltd. All rights reserved.
