Synthesis of magnoshinin and cyclogalgravin: Modified stobbe condensation reaction

The development of new methods for lignan synthesis is reported. A recently reported method for the preparation of 1-aryl-1,2-dihydronaphthalenes is exploited to prepare magnoshinin, a naturally occurring lignan, and cyclogalgravin (3,4-dehydrogalbulin), a derivative of a natural lignan.
