a) Interpretation: How to prepare the diol shown is to be stated. Concept introduction: A cis diol can be prepared by treating an alkene with osmium tetroxide. The addition of osmium tetroxide in to the alkene takes place with syn stereochemistry to produce a cyclic osmic ester which when cleaved using NaHSO 3 yields the cis diol. A trans diol can be prepared by acid catalyzed ring opening of epoxides with anti stereochemistry. The acid protonates the epoxide and then water attacks the protonated epoxide from the less hindered side to form an intermediate which deprotonates to yield a trans diol. To state: How to prepare the diol shown.

2) There are many forms of cancer, all of which involve abnormal cell growth. The growth and production of cells, called cell proliferation, is known to involve an enzyme called protein farnesyltransferase (PFTase). It is thought that inhibitors pf PFTase may be useful as anticancer drugs. The following molecule showed moderate activity as a potential PFTase inhibitor. Draw all stereoisomers of this compound.
