The synthesis of (4aR, 7aR) -octahydro-1H-pyrrolido [3,4-b] pyridine is a key research in the field of organic synthesis. There are many ways to synthesize it, and the following are common methods:
The starting material is selected from a suitable nitrogen-containing heterocyclic or unsaturated hydrocarbon compound, and the target product can be reached through a multi-step reaction. First, pyrrole and a suitable unsaturated olefin are used as the starting materials and undergo a cyclization addition reaction, which is the basis for the construction of pyrrolido-pyridine skeletons.
When cyclization is added, suitable catalysts and reaction conditions are required. For example, under the catalysis of high temperature or specific metal catalysts, pyrrole and olefins are cyclized by [4 + 2] to preliminarily construct a ring system. After that, after the hydrogenation step, the unsaturated bond is hydrogenated and reduced to obtain the structure of octahydro. During the hydrogenation process, common metal catalysts such as palladium carbon and platinum are reacted in a hydrogen atmosphere to saturate the double bond to meet the partial structural requirements of (4aR, 7aR) -octahydro-1H-pyrrolido [3,4-b] pyridine.
Furthermore, the nitrogenous five-membered ring and six-membered ring compounds can be used to start from the ring-opening and closed-loop reaction strategies. First, the starting material is functionally modified to have a check point for reactivity. Through reactions such as nucleophilic substitution and elimination, the ring system is rearranged and constructed, and the structure of the target product is gradually guided. This process requires precise control of reaction conditions, such as temperature, solvent, type and amount of base, etc., to ensure the selectivity and yield of the reaction.
In addition, asymmetric synthesis methods are also crucial. Because the target product has a chiral center, it is a (4aR, 7aR) -isomer of a specific configuration, and chiral catalysts or chiral auxiliaries can be used to induce asymmetric reactions. Chiral ligands combine with metal catalysts to selectively activate the substrate during the reaction, promoting the reaction to proceed in a specific chiral direction, and then obtaining a target product with high optical purity.
All the above synthesis methods require fine operation and strict reaction control to improve the yield and product purity to obtain the desired (4aR, 7aR) -octahydro-1H-pyrrolido [3,4-b] pyridine.
