Product Description
tert-Butyl 4-methylenepiperidine-1-carboxylate, also known as N-Boc-4-Methylenepiperidine, is a specialized nitrogen-containing organic compound with the CAS number 159635-49-1. It has a molecular formula of C₁₁H₁₉NO₂ and a molecular weight of approximately 197.27 g/mol. The compound features a piperidine ring protected by a tert-butoxycarbonyl (Boc) group and an exocyclic methylene group, making it a useful building block for organic synthesis and chemical intermediate development.
The combination of its protected nitrogen functionality and reactive carbon–carbon double bond provides opportunities for further structural modification in suitable synthetic routes. This compound may be considered for pharmaceutical intermediate research, heterocyclic compound synthesis, and fine chemical development. Its suitability depends on the intended target molecule, reaction conditions, and technical requirements of the customer.
Key Functions
Specialized building block for organic synthesis and intermediate development.
Boc-protected piperidine structure for selected synthetic routes.
Exocyclic methylene group for potential chemical transformations.
Potential starting material for the preparation of structurally diverse nitrogen-containing compounds.
Suitable for evaluation in pharmaceutical intermediate research and fine chemical synthesis.
Mechanism of Action
This compound is a chemical synthesis intermediate rather than a finished pharmaceutical ingredient. Its chemical reactivity is associated with the exocyclic carbon–carbon double bond and the Boc-protected piperidine nitrogen. The double bond may participate in suitable addition, reduction, or other functionalization reactions, depending on the reagents and reaction conditions.
The Boc group serves as a protecting group for the piperidine nitrogen during selected synthetic steps. Under appropriate conditions, it may be removed to provide access to the corresponding nitrogen-containing intermediate for further chemical modification. The actual reaction pathway and suitability depend on the target structure and the established synthetic process.
Advantages and Benefits
Clearly identifiable chemical structure and CAS number.
Specialized piperidine-based molecular framework.
Reactive methylene functionality for selected synthetic transformations.
Boc protection supports controlled nitrogen functionalization strategies.
Suitable for evaluation in organic synthesis and chemical intermediate development.
