Chapter 15, Problem 49P

16-54 Several poisonous plants, including Atropa

belladonna, contain the alkaloid atropine. The name “belladonna” (which means “beautiful lady”) probably comes from the fact that Roman women used extracts from this plant to make themselves more attractive. Atropine is widely used by ophthal mologists and optometrists to dilate the pupils for eye examination.

Chapter 15, Problem 49P, 16-54 Several poisonous plants, including Atropa belladonna, contain the alkaloid atropine. The name

  1. Classify the amino group in atropine as primary, secondary, or tertiary.

  • Locate all stereocenters in atropine.
  • Account for the fact that atropine is almost insoluble in water (1 g in 455 mL of cold water) but atropine hydrogen sulfate is very soluble (1 g in 5 mL of cold water).
  • Account for the fact that a dilute aqueous solution of atropine is basic (pH approximately 10.0).

    13. (11pts total) Consider the arrows pointing at three different carbon-carbon bonds in the molecule depicted below. Bond B Bond A Bond C a. (2pts) Which bond between A-C is weakest? Which is strongest? Place answers in appropriate boxes. Weakest Bond Strongest Bond b. (4pts) Consider the relative stability of all cleavage products that form when bonds A, B, AND C are homolytically cleaved/broken. Hint: cleavage products of bonds A, B, and C are all carbon radicals. i. Which ONE cleavage product is the most stable? A condensed or bond line representation is fine. ii. Which ONE cleavage product is the least stable? A condensed or bond line representation is fine. c. (5pts) Use principles discussed in lecture, supported by relevant structures, to succinctly explain the why your part b (i) radical is more stable than your part b(ii) radical. Written explanation can be no more than one-two succinct sentence(s)! Google
