Abstract
Coupling of 7-methoxy-8-(3-methyl-2-butenyl)-2H-1-benzopyran (4a) with 2-chloromercurio-4,5-methylenedioxyphenol (5) yields (±)-6a, 12a-cis-dihydro-3-methoxy-4-(3-methyl-2-butenyl)-6H-[1,3]dioxolo [5,6]benzofuro[3,2-c][1]benzopyran (6; ±-4-prenylpterocarpin) in an efficient manner. An improved procedure for the preparation of chromenes is reported.Keywords
