Someone, somewhere once wished to experiment with new methods of reductive amination, but did not want to use expensive, difficult to obtain, or illegal ketones and aldehydes. Said something about it being pointless and uncool. Strange dude, really.
That person (was it a person, I wonder?), did, for some reason, want results obtained by reducing this ketone to apply to the aforementioned ketones and aldehydes. And so this person left a note, asking ning to put the question to the collective mind of the hive--what sort of ketone could this be?
Methyl ethyl ketone seems good, having a strangely familiar shape to it.
Or perhaps acetone, since it is so common?
Ning requests ideas, for curiosity knows no bounds.
