Piperidones

Piperidones are a class of chemical compounds sharing the piperidone skeleton. A classic named reaction for the synthesis of piperidones is the Petrenko-Kritschenko piperidone synthesis which involves combining an alkyl-1,3-acetonedicarboxylate with benzaldehyde and an amine.[1] This multicomponent reaction is related to the Hantzsch pyridine synthesis.

gollark: I don't think it's actually hugely relevant, unless you want to make it more efficient by doing greater-depth search around "important" things on the board.
gollark: I'm glad somebody does now.
gollark: Oh, good.
