New synthesis of cis-3,4-diaryl-1-tosylpyrrolidines
摘要:
Unsymmetrically substituted cis-3,4-diarylpyrrolidines are synthesized in nearly 25% overall yields starting from 4-aryl-1,2,5,6-tetrahydropyridines by iterative reactions using the combination of m-chloroperoxybenzoic acid (MCPBA) and boron trifluoride etherate (BF3 center dot OEt2) followed by Grignard addition, elimination and hydrogenation sequence.
