Question 1.

What is the predicted product when cholesterol is treated with acetyl chloride in presence of pyridine?

An illustration shows a partial reaction with no products mentioned. The reactant that has a SMILES string of C[C@H](CCCC(C)C)[C@H]1CC[C@@H]2[C@@]1(CC[C@H]3[C@H]2CC=C4[C@@]3(CC[C@@H](C4)O)C)C reacts with acetyl chloride in the presence of pyridine.

An illustration shows the structures of three compounds.Compound 1 has four fused ring systems, in which the first three are cyclohexane rings and the fourth ring is a cyclopentane ring. C 3 is wedge bonded to a chlorine atom, C 5 is double bonded to C 6, C 8 is wedge bonded to a hydrogen atom, C 9, C 14, and C 17 are each dash bonded to a hydrogen atom, C 10 and C 13 are wedge bonded to a methyl group, C 17 is further bonded to C 1 of a six-carbon chain. In the six-carbon chain, C 1 is dash bonded to a methyl group and wedge bonded to a hydrogen atom, C 5 is bonded to a methyl group. Compound 2 has four fused ring systems, in which the first three are cyclohexane rings and the fourth ring is a cyclopentane ring. C 3 is wedge bonded to an oxygen atom that is further bonded to a carbonyl group and the carbonyl carbon is bonded to a methyl group, C 5 is double bonded to C 6, C 8 is wedge bonded to a hydrogen atom, C 9, C 14, and C 17 are each dash bonded to a hydrogen atom, C 10 and C 13 are wedge bonded to a methyl group, C 17 is further bonded to C 1 of a six-carbon chain. In the six-carbon chain, C 1 is dash bonded to a methyl group and wedge bonded to a hydrogen atom, C 5 is bonded to a methyl group. Compound 3 has four fused ring systems, in which the first three are cyclohexane rings and the fourth ring is a cyclopentane ring. C 3 is wedge bonded to a hydroxyl group, C 5 is double bonded to C 6, C 8 is wedge bonded to a hydrogen atom, C 9, C 14, and C 17 are each dash bonded to a hydrogen atom, C 10 and C 13 are wedge bonded to a methyl group, C 17 is further bonded to C 1 of a four-carbon chain. In the four-carbon chain, C 1 is dash bonded to a methyl group and wedge bonded to a hydrogen atom, C 4 is double bonded to an oxygen atom and single bonded to a hydroxyl group.

Question 2.

What is the predicted major product when cholesterol is treated with peroxy acetic acid?

An illustration shows a partial reaction with no products mentioned. The reactant that has a SMILES string of C[C@H](CCCC(C)C)[C@H]1CC[C@@H]2[C@@]1(CC[C@H]3[C@H]2CC=C4[C@@]3(CC[C@@H](C4)O)C)C reacts with peroxy acetic acid.

An illustration shows the structures of three compounds.Compound 1 has four fused ring systems, in which the first three are cyclohexane rings and the fourth ring is a cyclopentane ring. C 3 is wedge bonded to a hydroxyl group, C 5 is double bonded to C 6, C 8 is wedge bonded to a hydrogen atom, C 9, C 14, and C 17 are each dash bonded to a hydrogen atom, C 10 and C 13 are wedge bonded to a methyl group, C 17 is further bonded to C 1 of an eight-carbon chain. In the eight-carbon chain, C 1 is dash bonded to a methyl group and wedge bonded to a hydrogen atom, C 5 is bonded to a methyl group. Compound 2 has four fused ring systems, in which the first three are cyclohexane rings and the fourth ring is a cyclopentane ring. C 3 is wedge bonded to a hydroxyl group, C 5 and C 6 are each bonded to a hydroxyl group, C 8 is wedge bonded to a hydrogen atom, C 9, C 14, and C 17 are each dash bonded to a hydrogen atom, C 10 and C 13 are wedge bonded to a methyl group, C 17 is further bonded to C 1 of a six-carbon chain. In the six-carbon chain, C 1 is dash bonded to a methyl group and wedge bonded to a hydrogen atom, C 5 is bonded to a methyl group. Compound 3 has four fused ring systems, in which the first three are cyclohexane rings and the fourth ring is a cyclopentane ring. C 3 is wedge bonded to a hydroxyl group, C 5 and C 6 are dash bonded to a common oxygen atom that forms an epoxide ring, C 8 is wedge bonded to a hydrogen atom, C 9, C 14, and C 17 are each dash bonded to a hydrogen atom, C 10 and C 13 are wedge bonded to a methyl group, C 17 is further bonded to C 1 of a six-carbon chain. In the six-carbon chain, C 1 is dash bonded to a methyl group and wedge bonded to a hydrogen atom, C 5 is bonded to a methyl group.
