Chapter 26, Problem 26.38P

Although diazomethane ( CH 2 N 2 ) is often not a useful reagent for preparing cyclopropanes, other diazo compounds give good yields of more complex cyclopropanes. Draw a stepwise mechanism for the conversion of diazo compound A to B, an intermediate in the synthesis of sirenin, the sperm attractant produced by the f emale gametes of the water mold Allomyces.

Although diazomethane (CH2N2) is often not a useful reagent for preparing cyclopropanes, other diazo compounds give good yields of more complex cyclopropanes. Draw a stepwise mechanism for the conversion of diazo compound A to B, an intermediate in the synthesis of sirenin, the sperm attractant produced by the female gametes of the water mold Allomyces.
Draw a stepwise mechanism for the following reactions, two steps in R. B. Woodward’s classic synthesis of reserpine in 1958. Reserpine, which is isolated from the extracts of the Indian snakeroot Rauwola serpentina Benth, was used at one time to manage mild hypertension associated with anxiety.
A key step in the synthesis of β-vetivone, a major constituent of vetiver, a perennial grass found in tropical and subtropical regions of the world, involved the reaction of compound A and dihalide B with two equivalents of LDA to form C. Draw a stepwise mechanism for this reaction. β-Vetivone contains a spiro ring system—that is, two rings that share a single carbon atom.
