Suppose you are trying to synthesize the dipeptide Val-Ser.

Suppose you are trying to synthesize the dipeptide Val-Ser. Compare the product that would be obtained if thionyl chloride were used to activate the carboxyl group of N-protected valine with the product that would be obtained if it were activated with DCCD.

1)Draw the products which obtained if thionyl chloride is used to activate the carboxyl group of N-protected valine. 2)Draw the products which obtained if DCCD is used to activate the carboxyl group of N-protected valine.
