2- 1-propanone

So let s say, for instance, that some deranged lunatic did the exact opposite of what this book says, and went ahead and got some equipment, a couple of chemicals and some safrole, isosafrole and/or the precursor of their choice. They may very well decide to do something to it to get it farther along the path to final product. Well, currently on the place called Earth, the most widely made precursor for X and amphetamine production is the phenylace-tone. For crystal meth the precursor is called just that phen-ylacetone (a.k.a. phenyl-2-propanone, a.k.a. P2P). For X the precursor would be called 3,4-Methylenedioxyphenylacetone (a.k.a 3,4-Methylenedioxy-phenyl-2-propanone, a.k.a. MD-P2P). Strike knows it should technically be written as MDP-2-P, but Strike has always written it incorrectly as MD-P2P and that is just how stupid-ass Strike is always gonna refer to it. 

Chloroacetone, phenacylbromide, a-bromoisobutyrophenone, 3-bromo-3-methyl-2-butanone, 1 -alkylsulfonyl-3-bromo-2-propanone, and ethyl-y-chloroacetoacetate give with ammonium dithiocarbamate the corresponding 4-hydroxythiazolidine-2-thiones (177), which have a characteristic absorption between 273 and 279 nm. Dehydration by heating with dilute HCl can be followed by ultraviolet spectroscopy because the products formed (175) absorb at 315 to 340 nm. 

The longest continuous chain contains three carbons and C 2 is the carbon of the carbonyl group The substitutive lUPAC name for this ketone is 7 3-diphenyl-2- propanone ... 

Some trivial names are retained acetone (2-propanone), biacetyl (2,3-butanedione), propiophen-one (CgHj—CO—CH2CH3), chalcone (C(,H5—CH=CH—CO—CgH5), and deoxybenzoin (C<,H5—CH3—CO—C H ). 

In this thiamine pyrophosphate-mediated process, ben2aldehyde (29), added to fermenting yeast, reacts with acetaldehyde (qv) (30), generated from glucose by the biocatalyst, to yield (R)-l-phen5l-l-hydroxy-2-propanone (31). The en2ymatically induced chiral center of (31) helps in the asymmetric reductive (chemical) condensation with methylamine to yield (lR,23)-ephedrine [299-42-3] (32). Substituted ben2aldehyde derivatives react in the same manner (80). 

Chemically, wood tar is a complex mixture that contains at least 200 individual compounds, among which the foUowing have been isolated (1) 2-methoxyphenol, 2-methoxy-4-ethylphenol, 5-meth5i-2-methoxyphenol, 2,6-x5ienol, butyric acid, crotonic acid, 1-hydroxy-2-propanone, butyrolactone, 2-methyl-3-hydroxy-4JT-pyran-4-one, 2-methyl-2-propenal, methyl ethyl ketone, methyl isopropyl ketone, methyl furyl ketone, and 2-hydroxy-3-methyl-2-cyclopenten-l-one. 

All known commercial syntheses are based on this approach with improvements in preparations of the three components (23). Shordy after the first synthesis, similar methods were pubUshed employing other C -halo compounds, such as l,l,3-tribromo-2-propanone, 2,2,3-tribromopropanal (24), 2,2,3-trichloropropanal, and l,l,3-trichloro-2-propanone (23).
