Question

4. Draw the product of the following reactions. Pay attention to regio- and stereoselectivity of each of these transformations. Explain your answers using renderings of reaction mechanisms and/or transition states of the transformations, он 1) 2 eq. LDA 2) CH3l, HMPA

, the starting material is not only a ketone but also a halide. This means that you should generate a nucleoophile, which then reacts intramolecularly.

    Draw the missing major organic product(s), starting material(s), or reagents for each of the following reactions (DO NOT WRITE +EN AS A PRODUCT (ie draw everything out!)! And remember stereo and regiochemistry.) Assume reagents are in excess unless otherwise indicated. **To make things simple, I indicated what is needed for each section! Please don't just put the answers, but explanations as well on why. Thanks! a) draw the starting material for this reaction. b) draw the product for this reaction....

    Take the following compound, benzoquinone, which is considered a 'readily available starting material' in this task. Devise a 7 step synthesis starting from benzoquinone (i.e. create your own target molecule). You may use any chemically reasonable reactions and any other reagents as necessary, however, there must be two or more carbon-carbon bond forming reactions included. Strictly follow the requirements stated below to complete this task: 1) Present the synthesis as a reaction scheme, giving all reagents and any special reaction...

    i need help with the postlab questions please Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
