A certain class of natural products is formed in nature first by action of ADH-like enzymes on a starting material, followed by spontaneous (non-enzyme-catalyzed) steps that generate the final structure. One such product, Compound P, was formed when the ADH-like enzyme was provided with NAD²H₂ as cofactor. (As a reminder, NAD²H₂ is NADH wherein both transferable hydrogens have been replaced by deuterium.) 1. ADH-like enzyme, NAD²H₂ ° 2. spontaneous steps Starting Material I I OH Compound P Using NAD²H₂ as cofactor, provide a complete curved-arrow mechanism for this transformation. Make sure your mechanism accounts for the location of the deuterium in the product. For the spontaneous steps, you may use general acids and bases, but no other cofactors. (Hint: numbering your carbons will be helpful.)
One possible way of determining the identity of an alkene, is to let itundergo an oxidative cleavage reaction in the presence of hot basicpotassium permanganate. You are given two containers said to containdifferent alkenes. Container A is marked as cis / trans‐2‐butene andcontainer B as 2‐methyl‐1‐butene. Explain by referring to the formation ofproducts, how you would verify the identity of the alkenes.

Compound 1 has been shown to be a useful precursor in the synthesis of natural products. (Org. Lett. 2004, 6, 4439-4442). In principle, four stereoisomers are possible when this compound is subjected to catalytic hydrogenation. Draw these stereoisomers and describe their relationships. HO O OH H₂ - ?

Treatment of a cyclic ketone with diazomethane is a method for accomplishing a ring-expansion reaction. The reaction involves the initial nucleophilic attack by diazomethane on the carbonyl carbon to form a tetrahedral intermediate. Collapse of this intermediate is accompanied by bond migration and loss of N,. For example, treatment of cyclohexanone with diazomethane yields cycloheptanone. CH2N2, ether + N2 Draw the structure of the organic product(s) of the ring expansion of this compound: • You do not have to consider stereochemistry. • You do not have to explicitly draw H atoms. • Do not include lone pairs in your answer.
