- Doxaprost, an orally active bronchodilator patterned after the natural prostaglandins , is synthesized in the following series of reactions starting with ethyl 2-oxocyclopentanecarboxylate. Except for the Nef reaction in Step 8, we have seen examples of all other types of reactions involved in this synthesis. Q. Step 9 is done by a Wittig reaction. Suggest a structural formula for a Wittig reagent that gives the product shownOver the past several decades, chemists have developed a number of synthetic methodologies for the synthesis of steroid hormones. One of these, developed by Lutz Tietze at the Institut für Organische Chemie der Georg-August-Universität, Göttingen, Germany, used a double Heck reaction to create ring B of the steroid nucleus. As shown in the following retrosynthetic analysis, a key intermediate in his synthesis is compound (1). Two Heck reaction disconnects of this intermediate give compounds (2) and (3). Compound (2) contains the aromatic ring that becomes ring A of estrone. Compound (3) contains the fused five- and six-membered rings that become rings C and D of estrone.

A geminal dihalide is produced by the hydrohalogenation reaction.II. The proton in the terminal carbon is acidic but just slightly.III.They create an aldehyde when they react with H2O, H2SO4, and HgSO4.IV. A silver acetylide is formed after treatment with alcoholic AgNO3.
- Prostaglandins (Section 26.7) are a group of structurally related compounds that function as biochemical regulators and exhibit a wide array of activity, including the regulation of blood pressure, blood clotting, gastric secretions, inflammation, kidney function, and reproductive systems. The following two-step transformation was employed by E. J. Corey during his classic prostaglandin synthesis. Identify the reagents that you would use to convert compound 1 to compound 3 and draw the structure of compound 2.16. When cis-1,2-cyclopentanediol reacts with acetone in dry HCl, compound M is formed. What do you expect the hydrolysis of compound M to be when subjected (i) to base; and, (ii) acid a. resistant to base; resistant to acid b. resistant to base; readily hydrolyzed by acid c. readily hydrolyzed by base; resistant to acid d. readily hydrolyzed by base; readily hydorlyzed by acid 17. Following (16), would you expect that a similar compound be formed if the reactant was trans-1,2-cyclopentanediol? Why is this so? a. Yes; hydroxyl groups are on opposite side b. No; hydroxyl groups are on opposite site c. Yes; hydroxyl groups are on the same side d. No; hydroxyl groups are on the same sideDoxaprost, an orally active bronchodilator patterned after the natural prostaglandins , is synthesized in the following series of reactions starting with ethyl 2-oxocyclopentanecarboxylate.
