Question
**Title: Reaction Pathway Problem**

**Instruction:**
For each of the following questions, please provide a route that could reasonably be expected to convert the starting material into the final product. In each case, more than one reaction is required, and reactions you have learned in previous chapters may be needed to solve the problem.

**Reaction Pathway Diagram:**

- **Starting Material:**
  - Structure: A linear carbon chain with a terminal alkyne group and a ketone (carbonyl) group three carbons from the end.
  - Notable Features: Terminal alkyne (triple bond) adjacent to an ethyl group, and a ketone group.

- **Reaction Arrow:**
  - Indicates a transformation from the starting material to the final product.

- **Final Product:**
  - Structure: A cyclopropane attached to a linear carbon chain, with a ketone group three carbons from the cyclopropane.
  - Notable Features: Cyclopropane ring, indicating the presence of a new three-membered carbon ring, and the ketone group remains in the same position as in the starting material.
  - Stereochemistry: Marked with (±), indicating the formation of a racemic mixture.

**Explanation:**
Explore potential reaction mechanisms involving cyclization and stereochemical considerations to achieve the transformation from the alkyne-containing starting material to the cyclopropane final product.
