Have been stuck trying to propose a synthesis for this fragment for a long time. The ideas I have had so far are nitrile aldol (nitrile + aldehyde) or mannich reaction), but cannot figure out how to obtain stereoselectivity. Is there a simpler solution I am overlooking? submitted by /u/memer4242 [visit reddit] [comments ..read more

I was trying to see if maybe a Nh2 could become the NMe2 but Im stumped submitted by /u/MaybeCompetitive1394 [visit reddit] [comments ..read more

Hey guys, I have my ochem final pretty soon and the one thing that is really tripping me up this unit is differentiating between a good nucleophile and a poor nucleophile in substitution and elimination reactions. Is there some kind of trick I can learn to identify a good vs poor nucleophile immediately? And how does this relate to basicity? I know a good nucleophile is typically a strong base, but when is a weak base a good nucleophile? submitted by /u/sunjaw53 [visit reddit] [comments ..read more

I am confused about how to explain the electron cloud of the aromatic ring based on the substituents and how we can explain the pi-pi stacking based on that. What concept do we use to describe this? In detail, the benzene ring has an electron crowd around the aromatic ring because of the presence of pi—-electrons. If we make substituents that are EW or ED, how does that affect the electron-cloud? ​ submitted by /u/Ok_Switch_9728 [visit reddit] [comments ..read more
