Cofty and K99 Thanks for the link. I read it and checked some references and this is what I found.......

I
don’t find this source credible. The website is called nature publishing group.
Is this group run by chemists or other people who don’t have scientific
credentials?
Cofty, I
asked you to go back and reread the paper and quote directly from the paper
where he stated he solved the puzzle but you didn’t do that. Why not?
So
I went to every cited Soai reference and this is what I found
Abstract
Optically
active 1-(3-pyridyl)alkanols, chiral self-catalysts, produced themselves of the
same configuration in the enantioselective addition of dialkylzinc reagents to
pyridine-3-carbaldehyde.

The PDF was almost £40 so
I didn’t read it.
Abstract
Chiral diols,
bis[2-(1-hydroxyalkyl)phenyl]ethers, with very high e.e.'s are synthesized by
catalytic enantioselective alkylation of bis(2-formylphenyl)ether. Zinc
alkoxides of chiral diols were found to work as asymmetric autocatalysts in the
reaction between bis(2-formylphenyl)ether and dialkylzincs.

Abstract
Isopropylzinc alkoxide
of 1-ferrocenyl-2-methylpropan-1-ol was found to be a catalytic chirally
self-replicating molecule which produces itself with the same configuration
from ferrocenyl aldehyde and diisopropylzinc with 35–39% e.e. in good yields.

Note: In lieu of
an abstract, this is the article's first page.
The
first page is just a list of contents
http://pubs.acs.org/doi/abs/10.1021/cr00013a004
So I went to download the
PDF and it stated that I do not have the credentials
Note: In lieu of
an abstract, this is the article's first page.
This first page was an
interesting read, nowhere did Soai state it was a puzzle or a mystery. It was
very interesting though that he used the term design when describing a
molecule. I am not reading anything into it as I feel the whole page is
impartial. Just think it’s interesting.
“On the other hand from
the standpoint of the design of chiral catalyst a chiral alcohol with a
sterically bulky secondary substituent isopropyl shows higher asymmetric
induction……..”
When you read the whole
page in context, I would be interested to know if you do, it’s clear he is not
suggesting there is a designer for the
molecule, he is not talking about God or Atheism. He is talking about specific
research and it’s application. So I sincerely don’t want to mislead any
believers into thinking Soai believes in God or a creator.

Japanese
religions are very interesting . I got a little distracted and had a read.
Sorry to go off topic.

Bact to topic. All of
these are abstracts from different papers doing different research to develop
different products. I can’t find anything where Soai states the following
THE homochirality of natural amino acids and sugars remains a puzzle for
theories of the chemical origin of life1–18. In 1953 Frank7 proposed a reaction scheme by which a
combination of autocatalysis and inhibition in a system of replicating chiral
molecules can allow small random fluctuations in an initially racemic mixture
to tip the balance to yield almost exclusively one enantiomer. Here we show
experimentally that autocatalysis in a chemical reaction can indeed enhance a
small initial enantiomeric excess of a chiral molecule. When a 5-pyrimidyl
alkanol with a small (2%) enantiomeric excess is treated with diisopropylzinc
and pyrimidine-5-car-boxaldehyde, it undergoes an autocatalytic reaction to
generate more of the alkanol. Because the reaction involves a chiral catalyst
generated from the initial alkanol, and because the catalytic step is
enantioselective, the enantiomeric excess of the product is enhanced. This
process provides a mechanism by which a small initial imbalance in chirality
can become overwhelming.
That’s what the
website states there is no proof Soai wrote it in any of his research yet. I
have tried to find the links Cofty sent me with the actual paper on JWN but neither
of us started the thread, so I am having problems finding that specific paper.
I also tried to google it and I mustn’t
be very good at finding stuff because I can’t find this 1995 paper that
I have read multiple times.
What is CAS
reference linking? Cofty is it Your way of seeking the best possible argument
against your position, or confirming your position / bias? Semantics.
Cofty, I am going
to respond to your challenge. I have a response that’s not complete in writing.
But you have not responded to my challenge properly have you?
I
asked you to go back and reread the paper and quote directly from the paper
where he stated he solved the puzzle or mystery but you didn’t actually do that
did you?
So
I am requesting respectfully that you do this for me please. I am happy for you
to prove me wrong. I respect Soai more than Dawkins, so knowing what respected
chemists believe may influence my thinking and I could change my opinions with
new facts I learn.
