Concept explainers
Interpretation:
The routes for the reactions that could form the desired products are to be provided.
Concept introduction:
The Heck Mizoroki reaction is a coupling reaction between an alkene and an alkenyl or aryl halide in the presence of a palladium catalyst and a base, usually an
Ring closing metathesis is a process in
The Suzuki Miyaura coupling is a palladium catalyzed reaction in which an alkenyl or aryl borate couple reacts with an alkenyl or aryl halide. In this reaction, the stereochemistry of reactants is retained in the products.

Identify the successful approach (A or B)arrow_forward(19, 8, 1) Specify a synthetic scheme that would produce the compound shown above in the fewest steps possible. Use one of the starting materials shown together with any of the available reagents. Give the number of the starting material followed by the letters of the reagents in the order of their use, for example: 3be.arrow_forward
- Provide a mechanism which explains the following conversions. Include all intermediates (where appropriate) and watch your arrows and chargesarrow_forwardUse line structures and write the mechanism for the first and second steps of the hydrobromination reaction of compound C in the presence of HBr to demonstrate that it is a regioselective reaction. Clearly indicate the following: a) the flow electrons in step 1 and in step 2 and b) draw the product D(product 2) resulting from step 2. Include stereo chemistry in your answer.arrow_forwardCompound A is an alcohol that undergoes oxidation to produce compound B.Compound B is a ketone that gives positive triiodomethane reaction. Compound B isthen reacted with phenyl magnesium bromide, C6H5MgBr in the presence of aqueousacid to form compound C. Compound C has the molecular formula of C9H12O.
