Synthesis of a bicyclic piperazine from l-aspartic acid and application of a fluoride-promoted SNAr coupling
The process development is reported of a pivotal C-N bond formation involving ((7R,9aS)-octahydro-1H-pyrido[1,2-a]pyrazin-7-yl)methanol (2) undergoing nucleophilic aromatic substitution with 3-chlorobenzo[d]isoxazole (3) to furnish ((7R,9aS)-2-(benzo[d]isoxazol-3-yl)octahydro-1H-pyrido[1,2-a] pyrazin-7-yl)methanol (4) as a key intermediate for a family of compounds (1). Essential to the success of the coupling is the use of fluoride in combination with a phase transfer catalyst. The development of an alternative route to bicyclic piperazine 2 that uses l-aspartic acid (20) as a starting material to avoid the need for a classical salt resolution is described.
Because enzymes can increase reaction rates by enormous factors and tend to be very specific, Synthetic Route of 16263-52-8, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about Synthetic Route of 16263-52-8
