Lecture 018: Wheel of Orgo II

We played "Wheel of Orgo" again today, with the modification that I only counted a point for reactions only if they were correct. Again 3 points for completing the synthesis. We did 2 relatively simple syntheses then started one difficult one (vanillin). We didn't get the chance to finish that one so we'll resume next time. Again Sujeet ended up with the most points at the end. I would encourage you to think of ways of finishing this synthesis with the reactions we have learned. It is a good way of consolidating the material in this class. You don't need to participate, you can pass your turn and you can join the game in progress. If you are taking the class online and would like to participate in a future Wheel of Orgo session email me so that I can plan future sessions.mp3 podcast Right-click and select "save target as" if downloading manually.pdf Right-click and select "save target as" if downloading manually.streaming screencast Flash

Lecture 028: Wheel of orgo 5

There were no questions for the exam so we did one last Wheel of Orgo to practice reactions from the whole course. There were 3 enol reaction patterns to identify in the first 2 syntheses. Then we synthesized a cat from glycine.mp3 podcast Right-click and select "save target as" if downloading manually.pdf Right-click and select "save target as" if downloading manually.streaming screencast Flash

Lecture 026: Extra Credit Help

Here are directions for completing the extra credit for this class. In the screencast I show how to:1) Download ChemSketch (only for Drexel students)2) Use wikipedia and Google scholar to find an article with a relevant synthetic step.3) Draw out the single step reaction with ChemSketch.4) Use Paint to convert the ChemSketch work into a bitmap file.5) Create a Flickr account to upload the bitmap file and create a tag. (Everyone in my classes use at least the "orgo" tag in Flickr.)6) Find the url referencing the picture in Flickr using properties and insert into a blog post. (I also go through creating a Blogger account)7) Give a brief description of the reaction and link to at least one peer-reviewed article.Notice that all the services are completely free. A freeware version of Chemsketch is available here. I don't know how it compares to the Drexel version.The example I used was the last step in the synthesis of ibuprofen - the hydrolysis of a nitrile. This is what it looks like.Remember the last day to have the extra credit work done is Friday June 3, 2005 at midnight.mp3 podcast Right-click and select "save target as" if downloading manually.There is no pdf for this lecture.streaming screencast Flash

Lecture 024: prob 12 d-h

We finished problem 12 on enol chemistry and completed the list of the patterns to look for in these syntheses. At the end of class I put up a few more problems of varying difficulty then assisted students in small groups. I'll post the solution to these on Wednesday. The test will be available Wednesday afternoon, a little earlier because Sunday and Monday Korman is closed. I will answer questions on Wednesday concerning the test then if there is any time left we'll do another Wheel of Orgo. Online students make sure to email me your questions. mp3 podcast Right-click and select "save target as" if downloading manually.pdf Right-click and select "save target as" if downloading manually.streaming screencast Flash
