In situ protection and deprotection of amines for iron catalyzed oxidative amidation of aldehydes
摘要:
An environmentally friendly synthetic route by the application of CO2 to synthesize amides via in situ protection and deprotection of amines for iron catalyzed oxidative amidation of aldehydes was developed. Various secondary and tertiary amides have been synthesized in moderate to good yields under mild and neutral reaction conditions. The use of amine hydrochloride salts and hence base for neutralization step is totally avoided in this protocol. (C) 2015 Elsevier Ltd. All rights reserved.

characterized using 1H and 13C nuclearmagneticresonance, infrared spectroscopy, and high-resolution mass spectrometry for the unpublished compounds. The compound 4-methoxy-benzyl 3,4,5-trimethoxybenzoate (9) presented an IC50 of 46.21 µM, high selectively (SI > 16), and caused apoptosis in SCC9 cancer cells. The molecular modeling study suggested a multi-target mechanism of action for the antitumor activity
