- Qa 18. Bromination of 5a-cholestan-3-one occurs at C-2 or C-4 to give 2 regioisomers. Two unsaturated ketones with lambdamax = 230 nm and lambdamax = 241 nm are yielded during dehydrobromination. Use Woodward-Fieser rules to distinguish between the two.The base-promoted rearrangement of an a-haloketone to a carboxylic acid, known as the Favorskii rearrangement, is illustrated by the conversion of 2-chlorocyclohexanone to cyclopentanecarboxylic acid. Jo Han Sow La NaOH, THF O Nat H3O+ OH NaOH, THF The mechanism involves the following 5 steps: -ō cyclopropanone intermediate 1. Abstraction of a proton to form enolate anion 1; 2. Formation of a cyclopropanone intermediate 2 with expulsion of chloride ion; 3. Addition of hydroxide ion to form tetrahedral intermediate 3; 4. Collapse of the tetrahedral intermediate and breakage of the three-membered ring to form carbanion intermediate 4; 5. Proton transfer to form the rearranged carboxylic acid. For the following reaction, draw the reaction out on paper, and then draw the structure of cyclopropanone intermediate 2 in the window. 1. NaOH, THF 2. H3O* OHWhat would be a proposed mechanism to get from cyclohexanol to cis-2-methoxycyclohexanol? I know how to get from cyclohexanol to trans-2-methoxycyclohexanol would be to go through acid-catalyzed dehydration via H2SO4, then epoxide ring formation via mCPBA and then alcohol-catalyzed opening, but don't know how to do for the cis version, if possible.
