I am trying to reproduce this figure in LaTeX:

The packages that I have seen for annotating chemical structures do not seem to accomplish what I want (not to mention that my knowledge on chemical notation has vanished long time ago).
So, any hint on how to perform this with TikZ/Asymptote/similar package?
asymptoteis your best bet if you want something properly 3D relatively easily. What you've posted isn't exactly like that so you could probably do it intikzfairly straightforwardly if that would be easier for you (e.g. you knowtikzbut notasymptote). What have you tried so far? – cfr Aug 20 '14 at 21:51tikzmaybe I should start with it. – epsilone Aug 21 '14 at 15:47
