Explain how Lankacidin C has double bonds in its backbone.

Solution

Lankacidin C utilizes \'Stille reaction\' for its synthesis. In Stille reaction, and organotin compound (Carbon linked to tin) is coupled with electrophile.

Electrophiles are electron loving. They lack electrons. So, they take electrons of the organotin compound and result in double bonds in the product (over here, Lankacidin C).
