(4aR,7aS)-6-benzyl-1-nitrosooctahydro-1H-pyrrolo[3,4-b]pyridine

(4aR,7aS)-6-benzyl-1-nitrosooctahydro-1H-pyrrolo[3,4-b]pyridine, also known as BNPP, is a chemical compound that belongs to the class of organic compounds known as pyrrolopyridines. It is a nitrogen-containing heterocycle that contains a pyrrolidine ring fused to a pyridine ring. BNPP is a yellowish crystalline powder that is soluble in organic solvents such as methanol, ethanol, and acetone but insoluble in water. BNPP is widely used in chemical research as a building block for the synthesis of many other organic compounds. It is especially useful in the development of drugs targeting the central nervous system, as it has been shown to have potent pharmacological effects on the brain. BNPP has been found to act as an antagonist at the N-methyl-D-aspartate (NMDA) receptor, which is involved in the regulation of synaptic plasticity and learning and memory processes. In terms of its chemical properties, BNPP contains a nitroso group (-NO) and a benzyl group (-CH2C6H5) attached to the pyrrolidine ring. The nitroso group is a highly reactive functional group that can participate in a variety of chemical reactions, including oxidation, reduction, and addition reactions. The benzyl group, on the other hand, is a common protective group in organic synthesis that can be easily removed under mild conditions to reveal the underlying functional group.
