摘要：

(Chemical Equation Presented) A palette of blues: Chlorobicyclo-[5.3.0] decatrienones are readily prepared from cycloheptatrienes by cycloaddition of dichloroketene, ring expansion with a diazoalkane, and dehydrochlorination in dimethylformamide. These compounds are used as intermediates in the regiocontrolled synthesis of a wide variety of natural and nonnatural azulenes (see scheme). © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
