According to Moody, the acquisition was not based on a desire to gain a position in chiral pool per se, but on the complementarity of technologies. When this test was applied to the picrate of tetrahydromorphitetrol XVa cis series the effect on the pH of 0. But if you are good and reliable and you can also offer a good portfolio of chiral technologies, then you really would be an interesting partner for pharma companies.
Morphine has five asymmetric carbon atoms: This article is dedicated to Dr. But he also emphasized that whatever methods are used, the bottom line is always economics.
It has been shown [ 7 ] , that the pH of 0. Schopf assumed that the probability for identical configuration at C 14 in both cases was high because hydrogenation of the 8,14 double bond in various compounds of this series, proceeds in only one steric sense. Durham Phil. There is no ironclad proof showing that the C 14 hydrogen in morphine and codeine has the same configuration' as the C 14 hydroxyl in 14-hydroxycodeinone V. Pharmaceutical companies expect suppliers to be up to the chiral challenges in the pipeline, and fine chemicals companies have been gearing up.
However, that reaction is noncatalytic because the chiral ligand is used in stoichiometric amounts. What's That Stuff? The information gleaned from various synthetic approaches to morphine will also be discussed, in so far as it may elucidate the steric configuration of the alkaloid or of certain of its degradation products. At present, AstraZeneca has at its disposal several routes to the compound. Shortly before, Handte had been reported elsewhere as having considered Clariant's life sciences operations, which includes the pharmaceutical business and custom synthesis units, "of less strategic importance" and as looking to divest them.
As Moody says of Avecia's acquisition of Synthon Chiragenics' fine chemicals business, "We're happy with the price we paid, obviously. Loss of half the yield of a complex-molecule product after resolution is untenable. Since the C 5 -O bond was not broken at any step of these transformations, the configuration at this point remains unaffected and the compound ultimately obtained XVa has a pair of vicinal hydroxyl groups at C 5 and C 6 with the original configurations at these carbon atoms retained.
Clariant's pharmaceutical business unit includes the company's regulated manufacturing sites and is responsible for servicing the pharmaceutical market. The economics are comparable with that of asymmetric routes in some cases and often can be improved by recycling and reracemization of the undesired enantiomer, he adds.
But as products of synthetic chemistry, chiral drugs until recently have had to be manufactured and used usually as racemates. Other commercial-scale chiral reactions are not based on chiral catalysis. Here again, we are dealing with a case in which the technique cyclization takes place in only one steric sense.
