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.

Un check up completo bioenergetico quantistico, indolore e veloce, eseguito con un’apparecchiatura frutto di 20 anni di studi – con test effettuati su più di 10.000 persone – dell’equipe medica del professore, biologo e fisico William Nelson. Nelson è stato nominato per il premio Nobel per la medicina, la ricerca e il contributo scientifico nel campo della medicina alternativa. L’apparecchiatura, chiamata SCIO, è stata ribattezzata Gioia Bertha dopo un primo difficile e importante caso risolto. Questa tecnologia è usata da anni negli ospedali pubblici e privati di Austria, Irlanda, Germania, Inghilterra, Usa e Canada. L’apparecchiatura SCIO si basa sulle scoperte più recenti della fisica quantistica, applicate alla medicina, e già usate dalla Nasa per la diagnosi e il trattamento a distanza degli astronauti in atmosfera; secondo le quali il benessere e la salute dipendono dalla corretta comunicazione tra le cellule. Comunicazione che avviene sotto forma di segnali elettromagnetici estremamente deboli ma con una frequenza ben definita. Se questa comunicazione armonica viene disturbata (a causa dello stress, di alimenti nocivi, geopatie ecc.) il corpo perde l’equilibrio e si manifestano sintomi che possono trasformarsi in malattie. SCIO è l’apparecchiatura esistente più avanzata, in grado di rilevare i cambiamenti elettromagnetici e di fare uno screening completo prima ancora che si manifestino i sintomi. Tra le altre cose rileva: allergie, intolleranze alimentari, funghi, batteri; geopatie; il livello di minerali e vitamine; intossicazioni di vario genere; lo stato di salute degli organi e dei sistemi (nervoso, linfatico ecc.) .

MacMillan's synthesis, highlighting the use of organocatalysis.

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

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.

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.

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.

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.

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.
