6a. On the answer sheet, draw molecule 1 and molecule 2 (at the indicated pH) and also draw their conjugate bases. (For any molecules you do not know, look up the structure on google/wikipedia/text). Based on ionic stabilization effects, which molecule would have a lower pKa for the group listed? Explain in 2-3 sentences. b. timt-1 molecule l molecule 2 pH group phenylalanine l...

1. Consider the synthesis of the following amino acids: a) write all the steps for the synthesis of valine starting with propane, using the HVZ reaction to make a bromo-acid, which is subsequently laminates. b)Write all the steps for the synthesis of leucine starting with isobutane and using the Gabriel-Malonic Ester reaction. Also, consider: I)how would the L-enantiomer of the amino acid be isolated from the racemic mixture resulting from the above reactions. ii) what would the mechanism be for...

Devise a synthesis of (Z)-4-methyl-2-pentene using one of the starting materials and any of the reagents below using the fewest steps possible. If you need fewer than the 3 steps allowed, enter "none" for reagents in the remaining unused steps. Starting materials HC=CH HC=C-CH, HC=C-CH,CH, сн. HC=C-CH2CH2CH2CH2HC=C-C-CH, von CH, HC=C-¢-CH, .

need help on synthesis
9 10-Synthesis question. Show how the starting material can be converted to the product through any of the reactions you have learned in Ochem-l and Ochem-II. 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 chiral molecule is formed mark the chiral center with an asterisk (*) and write "racemic" below the structure. All carbon...

Design a synthesis for 1-bromo-4-methyl-2-nitrobenzene using benzene as the starting material. You can handwrite everything. Please show the structures of the intermediates after each step as well as the reagents used. (NOTE: you can NOT use Friedel-Craft alkylation after Nitration.) ALSO, Professor said: ch3Br/FeBr3 --> Br/FeBr2 --> HNO3/H2SO4 OR Br2/FeBr2 -> CheCL/ALCL3 -> HNO3/H2SO4 would NOT work. Hint: need protecting group
