Organic Chemistry Random Reaction Generator?

[Thirty]

I need an online resource that will provide me with random organic reaction synthesis questions. Like along the lines of "X reacts with Y in Z solvent draw the expected organic product(s)". Anybody know of something like this?

That sounds a lot like my summer project! When are you needing it by?

The best way would be to buy a text book and do all the problems and use the sol manual to check the answer.

I found this a few weeks back. Might be of some use to you.

First semester a friend and I created synthesis problems for each other, and then solved them on a big white board. I highly recommend doing this. Make them as hard as possible, and the synthesis on your exams will be laughable. MIT opencourseware has a bunch of practice stuff as well.

+1 on openware classes. Even classes that aren't explicitly openware sometimes have materials that they don't mind sharing / never put password protection on it. I remember when I was going through orgo I was curious how my program compared to other programs as far as difficulty and scope. U Colorado had tons of practice exams which you may find helpful for synthesis problems. Having gone through my particularly rigorous orgo I am happy looking back on it. Narrowed what I had to study for the MCAT to really bio for the BS 👍

I have a problem for you,

(No advanced organic chemistry answer allowed)

I did it in about 13-15 steps. I'll upload my answer. Its a fun problem, give it a show.

I'll get around to this in the morning. The open courseware stuff looks decent, hopefully it'll help. Thanks for the replies. @TTigers70, I have an exam on Tuesday and I've already done all the problems in my textbook. Not sure if you'd be able to finish your summer project in a day, haha.

Dude....**** that.

Since they sold the program to wiley I don't think there is access to that many problems anymore but you can try: http://cdb.ics.uci.edu/cgibin/tutorial/ReactionTutorialSetupWeb.psp

Click on synthesis explorer, set the number to 5(max) and then select a topic from the list that you want the synthesis to relate to.

This would be nice

Looks useful. Bump for original topic.

the answer is this

I made a mistake counting carbons when I did this and I fixed but I never rescanned it, so I took a pic of it. Here it is.

Please keep in mind I did this at work, thats why its messy (usually I am way more neater) However I was told 3 people 2 Profs, 1 Chem Major my way ineffective because I will make the conjugated double bond. Since then I did come up with a new way to do the problem, I'll post that also once I find it.
Hope other found this to be as much fun as I did.

Wouldn't the step at the end where you add Br to the double bond also substitute the -OH group with Br as well? And in any case, grignard reagents don't react with alcohols...

 

[Godric]

I am adding a Hydrogen and Bromine across the double bond, and the Br will go to the secondary spot. I am not sure what you mean by substitute the OH group, OH is a poor leaving group. Afterwards adding Mg will make the the chain self react, that was the whole point. By creating the carbanion (once the Mg came in) it will attack the carbon where the OH is.
Correct me if i am wrong about this.
