1) What's the mechanism of the following reaction? NBS toluene, 48 hr, 15°C Is the product: Chiral Achiral (circle one) Is the product: Racemic Enantiopure Diasteromeric Mixture (circle one) 2) Diol 1 was prepared in one step (one pot - includes work-up) from what alkene? What reagents would you use to carry out this reaction? LOAC = ???

The target diol is synthesized in one step from
1-methylcyclopentene, but your lab partner exhausted the supply of
that alkene. Fortunately, you have plenty of isomers (C6H10) on
hand from which to synthesize 1-methylcyclopentene and, ultimately,
the diol. Provide the missing reagents and organic structures
needed to most efficiently produce the target product.

We learned that to create vicinal diols from alkenes, the cis-1,2-diol or trans-1,2 diol required very different reagents. This isn't always the case and one notable reaction that defies this convention is the Prévost reaction! (4 points) To make the cis-diol, we typically use osmium tetroxide (catalytic amounts!). What other reagent combination would work for this particular transformation? a. OH OH (rac b. (4 points) To make the trans-diol, what reagent combination would be employed? ?? 1F2 OH (4 points)...
