Reaction Conditions:
with tert.-butylhydroperoxide;manganese(II) triflate in water at 20; for 24 h;
Steps:
1 Example 1 Synthesis of 6,7-dihydro-5H-cyclopenta [b] pyridin-5-one
A solution of 0.883 mg of Mn (OTf) 2 (0.5 mol%), 60 mg of 2,3-cyclopentenopyridine, 0.35 g of 65% aqueous TBHP and 2.5 ml of water was added successively to a 25 mL round bottom flask, in the air at room temperature for 24 hours, the reaction solution was extracted with 3 x 5 mL of ethyl acetate, the ethyl acetate layer was collected, dried over anhydrous sodium sulfate, filtered and the ethyl acetate was distilled off, using petroleum ether and ethyl acetate in a volume ratio of 5: 1 as eluent, the product of 6,7-dihydro-5H-cyclopenta [b] pyridin-5-one 60.5 mg was obtained as a pale yellow solid in a yield of 91% by silica gel column chromatography.
