Chemistry-Proverbs (Important aspects of Chemistry research)
10 seconds labeling a sample saves 30 minutes identifying it later.
Knowing the chemistry of a reaction before running it once is better than running it ten times without knowing anything.
Just because you found it in literature doesn't mean it's correct
The more you learn, the dumber you feel
Troubles overcome are good to tell
One chemist's side product/decomp is another chemists target.
Cleanliness is next to success
The more you get,the more you want
Let it sit, and it goes to sh*&.
Gram in hand is worth two in the flask
Rearrangements happen.
Garbage in, garbage out
If you don't get what you like, try to like what you get.
The more you try the luckier you get.
Change or you will be changed
Too much analysis leads to paralysis
It's not the cage that sings, it's the bird inside.
The flask only falls when you are not there to catch it.
If it is highly colored, you will spill it on yourself.
The worse it smells, the greater chance that it will bump.
Chemistry is trying
The more you give the more you get
An hour a week on basics can yield advanced ideas
Education is the path from cocky arrogance to miserable insecurity
Love your chemistry, chemistry will love you!
The work isn't done until the pigs are fed, watered and ready to fly!
A week in the lab can save you a day in the library.
BOC-Pipirazines WILL foam!
When in doubt, throw it out.

Iterative Suzuki Miyaura Coupling Reaction
Iterative
Suzuki Miyaura Coupling Reactions
The Suzuki-Miyaura cross-coupling
reaction of boronic acids is one of the most important and highly utilized
reactions in the organic chemistry toolbox, with applications in polymer
science as well as in the fine chemicals and pharmaceutical industries. However,
many boronic acids are extremely unstable and susceptible to decomposition that
renders them inefficient in coupling reactions or makes long-term storage
difficult.
Iteration (lat. “iterare”=to repeat) is a powerful strategy employed in the biosynthesis of complex molecules. In these controlled iterative reactions, di- and multifunctional building blocks are employed that contain only one reactive functional group (“ON”), while all other groups are unreactive (“OFF”) thereby suppressing uncontrolled polymerization (Scheme 1). After the selective coupling of the reactive group, another, previously unreactive functional group is activated/deprotected (“ON”) and the coupling sequence repeated, thus allowing the efficient formation of defined oligomers from readily available building blocks. This enables even nonexperts to synthesize complex molecules in a short time, and promotes the rapid investigation and application of these compounds in chemistry and biology. An ideal iterative coupling would meet the following criteria:

An ideal iterative coupling would meet the following criteria:
ü Many
differently substituted building blocks are readily available and inexpensive;
ü Coupling
and activation/deprotection step are high yielding, are tolerant of many
different functional groups, and do not require nor produce toxic compounds;
ü Handling,
separation, and purification are facile;
ü The
iterative coupling sequence is reliable and predictable, which are important
aspects for applications in natural product synthesis and in industry;
ü The
sequence is suitable for solid phase synthesis and automation.

on Iterative Suzuki Miyaura Coupling reaction.
