Abstract: The catalyst-free Nazarov cyclization of aryl allenyl ketones under thermal condition is developed. Various densely functionalized 2,3-dihydroindanones or indenones are readily produced in moderate to excellent yields. Significantly, this procedure features high functional group tolerance… read more here.
