Could you explain how to do this with great detail?
![The alkyne hydrogenation reaction has been explored extensively by the Hoffmann-La Roche pharmaceutical company, where it is used in the commercial synthesis of vitamin A.
a) Fill in the box with the product(s) for the following reaction. Indicate the stereochemistry where appropriate.
- Reaction: Starting alkyne reacts with H₂ (excess) over a Lindlar catalyst to form a product.
- Diagram: The starting alkyne structure includes a triple bond at positions 7 to 8, adjacent to a series of conjugated double bonds ending in an alcohol group (OH). The hydrogenation involves the conversion of the alkyne to an alkene.
- Possible products:
- Product A
- Product B
- Product C
- Product D
[Select]
b) Choose the appropriate reagent(s) to obtain the hydrogenation product with trans-stereoconfiguration at the C7-C8 double bond, namely vitamin A.
