- D10) The above synthesis was designed using the Organic Chemistry Roadmaps in the appendix of your textbook. In this synthesis, reagents from the table are used to carry out the indicated steps (shown in blue). In the box below, draw the structure of compound c.Nitrating methyl benzoate. 1.Describe the mechanism of EAS clearly and in detail 2. What is the effect of subtituent of the outcome of EAS;include 3 classes of subtituentsOver 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. Q.Propose structural formulas for compounds (2) and (3).
