Over 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).

Q.Show how your proposals for compounds (2) and (3) can be converted to compound (1). (Note: In the course of developing this synthesis, Tietze discovered that vinylic bromides and iodides are more reactive in Heck reactions than are aryl bromides and iodides.)

In the course of the double Heck reactions, two new chiral centers are created. Assume in compound (3), the precursor to rings C and D of estrone, that the fusion of rings C and D is trans and that the angular methyl group is above the plane of the ring. Given this stereochemistry, predict the stereochemistry of…
In synthesizing primary (1⁰) amines by alkylation of NH3, explain how we can prevent the formation of 2⁰ and 3⁰ amines as by-products? You can give an example to help you in explaining but it is not required.
In preparation of p-Nitroaniline, Starting material is 50g of p-nitroacetanilide, 22ml of HCI, 20g of p-nitroaniline. Give % yield of nitro acetanilide. What is the objective of experiment? What is product prepared?
The pKas of chemicals HX and HY are 5 and 7 respectively. The pKa of carbonic acid H2CO3is 6. If you made up an ether solution of chemicals HX and HY in a separatory funnel, andthen added an aqueous solution of sodium bicarbonate NaHCO3 to that separatory funnel,would both HX and HY stay in the ether layer? Or would either or both of them transfer intothe aqueous layer? If one goes into the water layer, will it be in it’s neutral HX/HY form, or init’s deprotonated anionic form?
use your knowledge of acid-base extraction to come up with a plan to separate the following compounds from each other. Your plan should include specific solvents or reagents to be used and result in 4 isolated solids in the end. p-anisidine pyrene salicylic acid: 2,3-xylenol *Here is an hint and example: p=Anisidine is an amine, xylenol is a phenol, and salicylic acid has COOH and phenol groups. Always start with identifying the functional groups and you either add acids or bases to react then after you get your layer, you extract and normally you will get precipitation at the bottom and you collect it by vacuum iteration, solate the amine by extracting with HCl. The ammonium salt will be in the aqueous layer. Neutralize it by adding base (NaOH) until the solution is basic. Collect the amine(which we expect to precipitate) by vacuum filtration.
Describe how the product is purified. 4,4'-DIBROMOBIPHENYL [Biphenyl, 4,4'-dibromo-] Submitted by Robert E. Buckles and Norris G. Wheeler1. Checked by R. S. Schreiber, Wm. Bradley Reid, Jr., and Robert W. Jackson. 1. Procedure In a 15-cm. evaporating dish is placed 15.4 g. (0.10 mole) of finely powdered biphenyl (Note 1). The dish is set on a porcelain rack in a 30-cm. desiccator with a 10-cm. evaporating dish under the rack containing 39 g. (12 ml., 0.24 mole) of bromine. The desiccator is closed, but a very small opening is provided for the escape of hydrogen bromide (Note 2). The biphenyl is left in contact with the bromine vapor for 8 hours (or overnight). The orange solid is then removed from the desiccator and allowed to stand in the air under a hood for at least 4 hours (Note 3). At this point, the product weighs about 30 g. and has a melting point in the neighborhood of 152°. The crude 4,4'-dibromobiphenyl is dissolved in 75 ml. of benzene, filtered, and cooled to 15°. The…
