Question

U with 1) MurbA and 11) aqueous solution of sulfuric acid (k) with a cold, dilute solution of potassium permanganate with aqueous sodium hydroxide (no mechanism is needed for the second step). Also consider: what would the products be if the following reagents were used: i) osmium tetraoxide ii) aqueous solution of sodium sulfite? ALSO consider: how the products from all the reactions above would be different if the other geometric isomer was used and/or if the other enantiomer was used. 2. Predict the products for the oxidative cleavage of the reactant in problem-1; (a) with a hot, concentrated solution of potassium permanganate with aqueous sodium hydroxide (b) with i) ozon and ii) DMS ALSO consider: how the products from the reactions above would be different if the other geometric isomer was used and/or if the other enantiomer was used. 3. Starting with 2-methyl-butane, design the synthesis of: (No mechanism is needed) (a) 2-methyl-3-bromo-butan-2-ol (b) 2-methyl-butane-2,3-diol (c) acetone and acetic acid 8884

please do number 3 part A, B and C

Answer 1

based on the product conversions the possible reagents and the mechanisms are as follows
