Like other electrophiles, carbocations add to alkenes to form new carbocations, which can then undergo substitution or elimination reactions depending on the reaction conditions. With this in mind, consider the following reactions of nerol, a natural product isolated from lemon grass and other plant sources. Treatment of nerol with TsOH forms α-terpineol as the major product, whereas treatment of nerol with chlorosulfonic acid, HSO3Cl, forms a constitutional isomer, α-cyclogeraniol. Write stepwise mechanisms for both processes. Each mechanism involves the addition of an electrophile—a carbocation—to a double bond.

Determine all of the products obtained from the addition of HCl to the 1,3-diene. Once determined, draw a mechanism that accounts for the formation of every product. Then, Identify and account for the formation of the major adduct/or adducts under these conditions assuming that the reaction is conducted under thermodynamic conditions.

Use this information to demonstrate that the configuration of the alkene is preserved in the epoxide. As an illustration, show that reaction of cis-2-butene by this two-step sequence gives cis-2,3- dimethyloxirane (cis-2-butene oxide).arrow_forwardAlthough the Diels–Alder reaction generally occurs between an electronrich diene and an electron-deficient dienophile, it is also possible to have inverse-demand Diels–Alder reactions between suitable electrondeficient conjugated double bonds and electron-rich alkenes. These reactions are particularly useful because they allow for the incorporation of heteroatoms into the new six-membered ring. Predict the products of each inverse-demand Diels–Alder reaction below. Be sure your products reflect the correct stereochemistry. If more than one regioisomer is possible, draw both.arrow_forward

(b) Which is the structure of the isomer formed in 85% yield? How do you account for its formation? Create a model to help you make this prediction.arrow_forwardThe standard procedure for synthesizing a compound is the stepwise progress toward a target molecule by forming individual bonds through single reactions. Typically, the product of each reaction is isolated and purified before the next reaction in the sequence is carried out. One of the ways nature avoids this tedious practice of isolation and purification is by the use of a domino sequence in which each new product is built on a preexisting one in stepwise fashion. A great example of a laboratory domino reaction is William S. Johnsons elegant synthesis of the female hormone progesterone. Johnson first constructed the polyunsaturated monocyclic 3 alcohol (A) and then, in an acid-induced domino reaction, formed compound B, which he then converted to progesterone. A remarkable feature of this synthesis is that compound A, which has only one stereo-center, gives compound B, which has five stereocenters, each with the same configuration as those in progesterone. We will return to the chemistry of Step 2 in Section 16.7 and to the chemistry of Steps 3 and 4 in Chapter 19. In this problem, we focus on Step 1. (a) Assume that the domino reaction in Step 1 is initiated by protonation of the 3 alcohol in compound A followed by loss of H2O to give a 3 carbocation. Show how the series of reactions initiated by the formation of this cation gives compound B. (b) If you have access to a large enough set of molecular models or to a computer modeling program, build a model of progesterone and describe the conformation of each ring. There are two methyl groups and three hydrogen atoms at the set of ring junctions in progesterone. Which of these five groups occupies an equatorial position?
