( )-Jatrophone, a natural product isolated from the flowering plant Jatropha gossypiifolia, is known to function as a tumor inhibitor and has been used to treat cancerous growths. As part of the first total synthesis4 of ( )-jatrophone, compound 1 was prepared and then treated with compound 2 in the presence of Pd(PPh3)4 to give compound 3. Draw the structure of compound 3.

answer; /// i believe the correct answer is (reactants);

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

c should be the answer
