Compound A have the following characteristics:
molecular formula; only two signals in protonic NMR spectrum,
one of them near 6.0 ppm; in the infrared spectrum, there are two medium bands, one at 1670 cm-1 and another near 815 cm-1.
In a synthesis of compound E, the following sequence of reactions was used, starting from A:
Find the structures of compounds A through E.

Re: ORGANIC SYNTHESIS
Hey Swades, if you are using Latex, then make sure you enclose it within '[['.
Eg:
[[$x^2 + y^2$]]
Re: ORGANIC SYNTHESIS
Here s a simple one:
Synthesis atropine from succinaldehyde.
Re: ORGANIC SYNTHESIS
dei double mannich da …Rags u can post that in a new thread
Re: ORGANIC SYNTHESIS
yeah forgot da…
Re: ORGANIC SYNTHESIS
rags, i already posted dat question on aops. and shre, ill remember dat. how come the arrows are crooked?
Re: ORGANIC SYNTHESIS
I have no idea dude. Use this

Re: ORGANIC SYNTHESIS
is nmr spectrum there in jee syllabus??
Re: ORGANIC SYNTHESIS
no but i believe that it might be there for incho :)
Re: ORGANIC SYNTHESIS
no it isn't just there in InChO
Re: ORGANIC SYNTHESIS
isnt it there? OMG, our iit chem sir kept a special class for spectroscopy :D
Re: ORGANIC SYNTHESIS
it is there but only the basics. many problems do req the application of both nmr and ir. and its def dere for icho.
