The use of Grignard reagents in multi-step synthesis is widely employed. For each of the reaction sequences below, draw the major organic product that would be present after each reaction of the sequence. No mechanisms, no explanations, just draw the products (in total, 14 reaction products A to N are required). You may have to consult your lecture material and/or the textbook to solve some of these problems

please solve all 8. Provide an efficient multi-step synthesis of 2 starting with 1. In your forward synthesis, indicate the reagents used for each step by writing them over the arrow leading to cach of the specified products. At some point in your synthesis you must utilize the chemical(s) specified over the arrows. opo maeneo l 5. Draw the major product for each of the following reactions or reaction sequences. Show stereochemistry where appropriate. Assume aqueous workup. 1) Fe, HCI...
3) For the following multi-step synthesis. Provide the reagents needed for each step of the sequence and then write a paragraph that explains what has occurred overall synthetically and why this elaborate strategy is needed. HC 5- 0 HAC NMgBr
Design a multi-step synthesis for each of the following target molecules from the indicated starting material. Show the reagents needed for each step and the product of each step. Do not show any mechanisms. Draw the structures of the diene and the dienophile that reacted to form the Diels-Alder product shown. Provide the missing reagents in this multistep synthesis.
synthesis of triphenylmethanol draw reaction equation for the formation of the grignard reagent Load Reagents The left side of the arrow is for reactants, reagents (solvents etc.) must appear above or below the arrow, product(s) must be right of the arrow. You can use the "X" button to oneter a chemical formula. For further help see the help page. Note: only change a single atom into Mg using the X button, do NOT try to use the X as MgBr...
Organometallic reagents such as Grignard reagents, organolithium reagents and acetylides have two primary behaviors: 1) they act as strong bases, and 2) they act as strong nucleophiles. When they come into contact with any OH group they always act as a base and deprotonate the OH proton. Draw in curved arrows to show this deprotonation in the reactions below. Then, draw the missing organic products in each reaction. C-Na HOO- MgCl CH3CH20 'Na CH3co2 Li
