The Synthetic Routes of (S)-5-methoxy-1,2,3,4-tetrahydro-N-(phenylmethyl)- 2-Naphthalenamine (Rotigotine)

Introduction:

Rotigotine, also known as (S)-5-methoxy-1,2,3,4-tetrahydro-N-(phenylmethyl)-2-naphthalenamine, is a synthetic compound that is used in the treatment of Parkinson's disease.
It is marketed under the brand name Neupro and is a dopamine agonist that helps to alleviate the symptoms of the disease.
In this article, we will discuss the synthetic routes of Rotigotine and the importance of this compound in the chemical industry.

Synthetic Routes of Rotigotine:

There are several synthetic routes that can be used to synthesize Rotigotine, each with its own advantages and disadvantages.
Some of the most commonly used synthetic routes include:

1. Nitro-compound synthesis: This route involves the synthesis of a nitro-compound, which is then reduced to form Rotigotine.
   This method is relatively simple and cheap, but it can be hazardous due to the use of nitric acid.
   
2. Iminopiperidine synthesis: This route involves the synthesis of an iminopiperidine intermediate, which is then transformed into Rotigotine.
   This method is more complex than the nitro-compound synthesis, but it is safer and more efficient.
   
3. Pyrrole synthesis: This route involves the synthesis of a pyrrole intermediate, which is then transformed into Rotigotine.
   This method is more complex than the other routes, but it is safer and more environmentally friendly.
   

Advantages of Rotigotine:

Rotigotine has several advantages over other Parkinson's disease treatments, including:

1. Long duration of action: Rotigotine has a long duration of action, which allows for once-daily dosing and improved patient compliance.
   
2. Rapid onset of action: The onset of action of Rotigotine is rapid, with symptoms improving within 30 minutes of dosing.
   
3. Good oral bioavailability: Rotigotine has good oral bioavailability, making it easy to administer to patients.
   
4. Low protein binding: Rotigotine has low protein binding, which allows it to be used in patients with liver or kidney impairment.
