What would be the starting material for reductive amination?? figured that #1 and #2 is not bc lone pair of N is conjugated hence not much nucleophilic toward carbonyl. 
#3 also impossible bc adding phenyl to something is requiring EAS like mechanism 

am i in the right track? 
thanks

The image appears to depict a chemical reaction or series of reactions. Here's a transcription of the text and a detailed description of the chemical structures:

### Reaction Overview
1. **Unidentified Reactant:**
   - The starting material is depicted as a question mark within an incomplete cyclic structure, suggesting an unknown or unspecified reactant.

2. **Reaction Arrow:**
   - A standard arrow denotes the transition from reactants to products.

### Structures

#### Products

- The primary product is a cyclic amine structure:
  - A six-membered ring with an attached nitrogen atom.
  - Connected to an ethyl group and a phenyl (ph) group. 
  - Another benzyl ring is connected to the nitrogen atom.

1. **Structure 1:**
   - A six-membered ring (cyclohexane).
   - Attached nitrogen with one hydrogen (NH).
   - Phenyl group is attached to nitrogen.

2. **Structure 2:**
   - A six-membered ring with a primary amine group (N-H).
   - The ethyl group is attached to nitrogen.

3. **Structure 3:**
   - Ethyl amine with a nitrogen attached to a phenyl group.

### Notes
- Labeling under structures: Circled numbers (1, 2, and 3) are used to differentiate between the final products or steps in the reaction.

This description provides a general view of the potential chemical transformations, highlighting the significant changes in structure.
