Im taking med-chem and I was wondering if you had any suggestions to understanding some of the concepts. i.e. easy way to remember the Kreb cycle or the different uses for the many functional groups. thanks a bunch,
Clemmensen reduction of a,b unsaturated aldehyde	20 Jan 2004 20:44 GMT	3
Can a Clemmensen reduction be used in this example to reduce the aldehyde group to methyl without affecting the double bond? R-CH=CH-CHO -> R-CH=CH-CH3 Thanks
stability of carbokation(?) as in SN1 Reactions	20 Jan 2004 20:41 GMT	2
first, I am sorry for my bad english, but however i hope that you understand my problem. Can anyone please sort the following molecules in their stability in the transition state (don't know if that is the right word), with the first number representing the most stabil carbokation. ...
protein experiments	15 Jan 2004 19:11 GMT	1
I was wondering if anyone knows of a good experiment to do in a med chem class that deals with proteins or amino acids. I am looking for a synthisis, degradation, or extraction. I am open to any sugesstions or other possibilities.
4-amino salicylaldehyde	14 Jan 2004 20:35 GMT	1
I was going to synthesize some 7 substituted coumarins starting from 4-salicylaldehydes. The list of substituents would be chosen so that I would have a coumarin matching each benzene in the Johnson & Jankowski 13-C NMR catalog.
