piperidines การใช้

• Piperidines are resistant to an intramolecular Cope reaction but with pyrrolidine and with rings of size 7 and larger, the reaction product is an unsaturated hydroxyl amine.
• Phenothiazine antipsychotics are classified into three groups that differ with respect to the substituent on nitrogen : the aliphatic compounds ( bearing acyclic groups ), the " piperidines " ( bearing piperidine-derived groups ), and the piperazine ( bearing piperazine-derived substituents ).
• Ants attack and defend themselves by biting and, in many species, by stinging, often injecting or spraying chemicals, such as formic acid in the case of formicine ants, alkaloids and piperidines in fire ants, and a variety of protein components in other ants.
