The analysis of the chemical structure of N-tert-butoxycarbonyl-1,2,3,6-tetrahydropyridine is also related to the category of organic chemistry. The structure of this compound is composed of several parts ingeniously combined.
If it contains tert-butoxycarbonyl and tert-butoxycarbonyl, tert-butoxycarbonyl is connected to oxygen with tert-butyl (-C (CH < Br >) and then connected to carbonyl (-C = O), that is, -OC (= O) C (CH < Br >). This group is often used as a protective group for amino groups in organic synthesis. It can be introduced and removed under suitable conditions and plays an important role in many reactions.
Furthermore, the 1,2,3,6-tetrahydropyridine part, the pyridine ring is originally a six-membered nitrogen-containing heterocycle, which is aromatic. However, the 1,2,3,6 positions of the pyridine ring in this compound are hydrogenated, causing its aromaticity to disappear, forming an unsaturated six-membered ring structure with unique reactivity. The nitrogen atom is in the ring and has a lone pair of electrons, giving the ring certain alkalinity and nucleophilicity.
