4. propose the synthesis of preparing the target from its corresponding starting material. Show the product/s formed in each step. Mechanisms are not required. steps
Provide a sequence of reaction to convert the starting material to the product. Show all reagents and synthetic intermediates. You can use any addition carbon sources if needed but you must use the starting material given. The mechanisms do not have to be shown. Synthesis 1. The following transformations cannot be perfor Uwing transformations cannot be performed in one step. Provide a sequence of reactions 10 convert the "starting material" to the "product." Show all the reagents and synthetic intermediates....
99 - Synthesis questions. now the starting material can be converted to the product through any of the reactions you med in Chem-I. Show all the reagents you need and indicate the stereochemistry when opriate. You do not need to show arrow pushing like in a mechanism question, only the eactions. If a chiral molecule is formed mark the chiral center with an asterisk (°) and write below the structure. You may also draw both enantiomers and write RACEMIC in...
Propose the starting material for each product from a molecule with the given formula in the reactants box. You do not have to show mechanisms, but use any reagents you require for each problem. Each problem is ONE OF TWO retrosynthetic steps to the starting materials and all steps should be described CH, Br C Hia 4. Propose a mechanism for the reaction below, showing the movement of every pair of electrons. Draw in an energy diagram, labeling, with structures,...

(B) () Devise a synthesis of the following "target molecule" from the given starting material.(i) Also, expláin why you would make this "target molecule" this way rather than a one-step synthesis of monoalkylating ammonia (NH3). from: NH2 HN I TARGET MOLECULE Hydro lysis
012- Synthesis question A-L. Show how the starting material can be converted to the product through any of the reactions you have learned in O.Chem-I and O.Chem-I1. Show all the reagents you need and indicate the stereochemistry when appropriate. You do not need to show arrow pushing like in a mechanism question, only the reactions. If a racemic mixture is formed indicate the chiral center/s with an ASTERISK( and write racemic next to the structure. All carbon atoms should come...
