Synthetic Studies on a Picrotoxane Sesquiterpene, Coriamyrtin. II. An Effective Stereocontrolled Synthesis of the Picrotoxane Skeleton Except for a C1 Unit at the C9 Position and Functionalization of the Five-membered Ring

The picrotoxane skeleton (5) except for a C1 unit at the C9 position was effectively synthesized starting from protoanemonin and 2-methyl-1,3-cyclopentanedione through five steps.The key reaction of this synthesis was the Grignard re
