This is an experiment. It is NOT a presentation. It is meant to be an interactive pdf for students to work through/revise from at their own pace. For these features to operate I guess it needs to be downloaded first. It is based on 123.312 lectures on retrosynthesis or the design of chemical syntheses.

An introduction to total synthesis and retrosynthesis. A quick overview of retrosynthesis followed by one of the many syntheses of (–)-stenine. This is just an overview of the fascinating world of organic synthesis, it is not intended to teach retrosynthesis or organic synthesis. For that see some of my other lecture notes.

Chiral catalysis. This is a relatively brief look at some classic examples of chiral catalysis in organic synthesis. It gives a quick overview but does not go into any detail.

A look at epothilone A as it includes examples of many different forms of asymmetric synthesis. Also includes a little bit about ring-closing metathesis.

Synthesis of hirsutene. Here because I love the use of radicals in synthesis (and yes, this lecture includes a quick re-cap of radical chemistry).
123713AB lecture09
123713AB lecture09
Gareth Rowlands
MacMillan's synthesis, highlighting the use of organocatalysis.
123713AB lecture08
123713AB lecture08
Gareth Rowlands
Gives an introduction to total synthesis and why we do it (which reminds me, I must add a picture of Everest, as I think the fact that 'it is there' is the main reason for most syntheses). Then to introduce the topic with a reasonably simple synthesis, we will look at an example of the synthesis of Tamiflu.
123713AB lecture07
123713AB lecture07
Gareth Rowlands
The big topic of the last few years, the use of small organic molecules to catalyse enantioselective transformations. This lecture will start with proline before moving on to some of MacMillan's contributions to this field and, finally, finish with hydrogen bond catalysts and Brønsted acids.
123713AB lecture06
123713AB lecture06
Gareth Rowlands
This is the biggy, the one everyone wants to achieve. Here we will be looking at metal-based chiral catalysis. We will concentrate on bisoxazoline-based Lewis acid catalysis and then look at reductions before finishing with the ubiquitous Sharpless epoxidation and dihydroxylation.
123713AB lecture05
123713AB lecture05
Gareth Rowlands
Use of stoichiometric amounts of a chiral source. The usual suspects will be discussed, including borane reagents (mostly pinene derivatives) and the Brown allylation.
123713AB lecture04
123713AB lecture04
Gareth Rowlands
Self explanatory really, this lecture looks at chiral auxiliaries. We will concentrate on oxazolidinones in alkylations, aldol reaction and the Diels-Alder reaction. There will be a couple examples of other auxiliaries.
123713AB lecture03
123713AB lecture03

More substrate control, including allylic strain and directed reactions.
123713AB lecture02

General introduction to the course followed by a basic introduction to asymmetric or stereoselective Synthesis. Then starting the course proper by looking at substrate control.
123713AB lecture01
123713AB lecture01

The second set of tutorial questions on asymmetric synthesis. This one covers chiral reagents and starts enantioselective catalysis.

These slides are part of a talk to school teachers. They were designed to showcase some of the applications of organic chemistry, the range of natural and synthetic products. I'm not sure how much use it is without my commentary but, as always, it seems a waste to leave it on my hard drive. The second half gave a overview of chirality and stereoisomers as this topic often causes problems with students. This second half owes a lot to an excellent paper by Robert Gawley (J. Chem. Ed. 2005, 82, 1009) and just has prettier papers. This version of the talk includes a section I removed when presenting (due to time) on artificial sweeteners.
