Chapter 28, Problem 28.7P
Interpretation Introduction

Interpretation:

Both the conrotatory processes for the thermal electrocyclic conversion of (2E,4E)-2, 4- hexadiene into 3,4- dimethylcyclobutene is to be shown.

An explanation as to why the two processes are equally likely is to be stated.

Concept introduction:

Electrocyclic reactions are pericyclic reactions which takes place by concerted mechanism. These reactions involve ring opening or ring closure in a conjugated polyene.

In conrotatory, the end group atomic orbital rotates in a clockwise direction.

The natural product halomon could theoretically arise from another naturally occurring compound known as myrcene. To accomplish this, a biochemical process that could deliver the synthetic equivalent of BrCi to all three double bonds would be required. (Chem Comm. 2014, 50, 13725) (a) Using three molar equivalents of BrCL please provide a mechanism to account for the formation of the bracketed structure (you do not need to show stereochemistry in this mechanism) HB (3 equiv) myrcene balomon 8.61a Add curved arrow(s) to show the mechanism steps.

5.40. Give plausible products (or just one product) for each of the following reactions, or tell if no reaction is expected. (a) PDSO, + MgS > (b) (CH,),Hg + CaF, → 1. 1.
(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.
