Indane-l-one

Hallberg and coworkers [84] developed a synthesis of monoprotected 3-hydroxy-indan-l-ones 6/1-156 in moderate to good yields using salicylaldehyde triflates and...

Later it was described the synthesis of the donepezil HCI from 5,6-dimethoxy-2-(pyridin-4-yl)methylene-indan-l-one by the reaction with H2 over platinum dioxide at room temperature in acetic acid-methanol mixture to give 4-[(5,6-dimethoxy-l-indanon)-2-yl]methylpiperidine. The last one yielded donepesyl HCI by refluxing with benzyl bromide and triethylamine for 4 hours with the following addition of methanolic HCI (10%).
