Smith Ph.D." Subject: Re: CCL:Reaction Pathway Program Cc: CHEMISTRY #at# www.ccl.net In-Reply-To: <199707142145.AA14645;at;interlock.amoco.com> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Joe: I am not familiar with any program that will suggest ALL reaction pathways... there are just way too many possibilities, which is why we still have synthetic organic chemists. You are probably familiar with Bill Jorgensen's CAMEO program (I hope I have the name correct), which can suggest 'reasonable' synthetic routes to various types of compounds and functionality. There is also a commercial program (not that Bill doesn't sell his programs, ;)) called SYNTREE (I believe). There were some papers about this at either the last ACS National meeting in San Francisco or at the Midland, MI, ACS Regional meeting in May. I can look for more information if you wish, but I am at home and just finishing up a vacation while I write this. Regardless, both of these programs use a combination (I believe) of data bases and "expert" algorithms to select likely reactions. I don't know of anything that will give you all possible routes, except perhaps an aggressive undergraduate who has just finished his/her organic final exam. There was also SYNLIB that came from the late Dan Chodosh... I don't know if anyone picked up that program so I can't tell you if it still exists. This was purely data base based and matched based on user-defined descriptors, if I remember correctly from my postdoc days. MDL REACCS and CAS's reaction data base are two others that come to mind. I would also love to hear from anyone else about similar programs. Please post to CCL rather than just to Joe.
