Cahn–Ingold–Prelog rules

CIP rules are used to assign stereo chemistry of a molecule, at a chiral centre (R or S). There are many methods you can use to get the correct assignment- this is the one I use, and the one my university has taught me.

1) Orientate the molecule so that the atom with the lowest atomic number is facing away from you, in this case hydrogen.

2) Order the 3 atoms immediately bonded to the chiral carbon, with the atom of highest atomic number being 1st. Sulphur (atomic number of 16) is 1st and then Oxygen (atomic number of 8) is 2nd and Carbon (atomic number 6) is 3. 

3) Write the numbers 1,2,3 next to their atoms. If reading clockwise gives you 1, 2, 3 then you have an R- isomer. If you read anticlockwise gives you 1, 2 ,3 then you have an S- isomer. In this case we would read from Sulphur (1) to Oxygen (2) to Carbon (3) in an anticlockwise fashion and therefore this is the S isomer. 

This is different to the l and d (or + and -) assignment as this is based on its structure. l and d assignment is determined experimentally and have no correlation to R and S.

This 25-year-old lived for more than a year without a heart

Heart in a backpack!

A 25-year-old has just received a full heart transplant… but not before surviving for more than a year without a human heart inside his body.

Instead, Stan Larkin wore an ‘artificial heart’ in a backpack 24/7 for 555 days, which pumped blood around his body and kept him alive. The success of the procedure suggests that the device could be used to sustain other patients with total heart failure while they’re waiting for a donor.

Back in 2014, Stan became the first patient in Michigan to be discharged with the artificial heart device, which is known as a ’Syncardia’.

This sheet of paper can filter viruses right out of drinking water

So awesome.

Scientists have developed a simple sheet of paper that can filter tiny, disinfectant-resistant viruses right out of water - offering a cheaper way to make drinking water safe for millions of people in the developed world.

While researchers have done a pretty great job of coming up with easy ways for people to purify water in recent years, one thing they’ve struggled with is finding an affordable way to get small viruses out.

This new sheet of paper tackles that problem using layers upon layers of super-thin cellulose nanofibres - developed from green algae - and it’s been named the ‘mille-feuille’ or 'thousands leaves’ filter, after the French puff pastry. Delicious.

The Corey–Fuchs reaction.

On the picture there is the addition of the aldehyde to the triphenylphsosphine/carbon-tetrabromide reagent mixture at -78 °C in dichloromethane.

The Corey–Fuchs reaction  is also known as the Ramirez–Corey–Fuchs reaction, is a series of chemical reactions designed to transform an aldehyde into an alkyne. The formation of the 1,1-dibromoolefins via phosphine-dibromomethylenes was originally discovered by Desai, McKelvie and Ramirez. The second step of the reaction to convert dibromoolefins to alkynes is known as Fritsch–Buttenberg–Wiechell rearrangement. The overall combined transformation of an aldehyde to an alkyne by this method is named after its developers, American chemists Elias James Corey and Philip L. Fuchs.

Diels-Alder crystals, prior to recrystallization. The white product at the top is likely the Diels-Alder adduct in a fairly pure form; the greenish crystals below are also the adduct, but with oxidized anthracene impurities. These crystals were recrystallized from hot ethyl acetate.

Glassware setup for a Diels-Alder reaction with maleic anhydride acting as the dienophile and anthracene acting as the diene. The reactants were placed in a 5 mL conical vial and heated on an aluminum block; this method of heating allowed for the required level of temperature control.
