摘要:
A formal [4+3]-cycloaddition reaction of ortho-hydroxyphenyl-substituted para-quinone methides (p-QMs) with in-situ generated azaoxyallyl cations is reported. The reaction occurs under very mild reaction conditions (transition-metal free, room temperature, cheap inorganic base) and provides a very efficient route to a series of biologically important 1,4-benz...
