via what UaLelue type of mechanism? uur acid results in cyclohexanol and 2-methylpropene a. SN1 b. SN2 c. E1 d. E2 e. E1CB The biological conversion of chorismate to phenylpyruvate proceeds via a Claisen rearrangement yielding the intermediate prephenate, which is followed by a tandem decarboxylation and dehydration reaction to phenylpyruvate. Draw curved arrows to show the flow of all electrons, and indicate the two byproducts released in the second step. "H-A" is a general acid, "A-" is the conjugate base. 19 COO COO COO byproduct 1 byproduct 2 H-A
