An attempted synthesis of regioisomeric natural product zanthochilone has been described in brief with reversal of reduction selectivity.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">7</style></issue><custom3><style face="normal" font="default" size="100%">&lt;p&gt;Foreign&lt;/p&gt;</style></custom3><custom4><style face="normal" font="default" size="100%">Not Available</style></custom4><section><style face="normal" font="default" size="100%">3945-3950</style></section></record></records></xml>
