The enantiospecific synthesis of chromanes and isochromanes using a variant of an intramolecular Nicholas reaction
摘要:
The enantiospecific synthesis of chromanes and isochromanes obtained from an intramolecular Nicholas cyclisation reaction is discussed. During the course of this study we observed the formation of chroman-4-ones from a CAN deprotection step of a dioxolane and this is also discussed. (c) 2012 Elsevier Ltd. All rights reserved.
