Reengineered carbonyl reductase for reducing methyl-substituted cyclohexanones.
The carbonyl reductase from Candida parapsilosis (CPCR2) is a versatile biocatalyst for the production of optically pure alcohols from ketones. Prochiral ketones like 2-methyl cyclohexanone are, however, only poorly accepted, despite CPCR2's large substrate spectrum. The substrate spectrum of CPCR2 was investigated by selecting five amino positions (55, 92, 118, 119 and 262) and exploring them ...
متن کاملtrans-Di-μ-carbonyl-bis{carbonyl[η5-2,3,4,5-tetramethyl-1-(5-methyl-2-furyl)cyclopentadienyl]ruthenium(I)}(Ru—Ru)
In the crystal structure of the title compound, [Ru(2)(C(14)H(17)O)(2)(CO)(4)], each Ru(I) atom is connected to one end-on and two bridging carbonyl groups and one cyclo-penta-dienyl ring. The two Ru atoms are connected into binuclear complexes via two bridging carbonyl groups, forming four-membered rings which are located on centres of inversion. The Ru-Ru distance of 2.7483 (11) Å corresponds...
متن کاملtrans-Di-μ-carbonyl-bis{carbonyl[η5-2,3,4,5-tetramethyl-1-(2-thienyl)cyclopentadienyl]ruthenium(I)}(Ru—Ru)
The title compound, [Ru(2)(C(13)H(15)S)(2)(CO)(4)], is a centrosymmetric binuclear metal-carbonyl complex containing an Ru-Ru single bond [2.7511 (8) Å]. Each Ru(I) atom is coordinated by two bridging carbonyl ligands, one terminal carbonyl ligand and one η(5)-cyclo-penta-dienyl group. The complex has a trans conformation and the two cyclo-penta-dienyl ring planes are parallel. The crystal stru...
متن کاملNovel polycarbo-substituted alkyl (thieno[3,2-c]quinoline)-2-carboxylates: synthesis and cytotoxicity studies.
Direct one-pot base-promoted conjugate addition-elimination of 6,8-dibromo-4-chloroquinoline-3-carbaldehyde with methyl mercaptoacetate and subsequent cyclization afforded methyl [(6,8-dibromothieno[3,2-c]quinoline)]-2-carboxylate. The latter undergoes Suzuki-Miyaura cross-coupling with arylboronic acids to yield exclusively the corresponding alkyl [(6,8-diarylthieno[3,2-c]quinoline)]-2-carboxy...
متن کاملBenzothiazole- and benzoxazole-substituted pyridine-2-carboxylates as efficient sensitizers of europium luminescence.
A facile synthesis of benzothiazole- and benzoxazole-substituted pyridine-2-carboxylic acids has been developed. These ligands form mononuclear nine-coordinate complexes [Ln(kappa(3)-ligand)(2)(kappa(1)-ligand)(H(2)O)(2)] with light and heavy trivalent lanthanides, as established from the X-ray analysis of 11 complexes. A crystal structure of a minor product, the anhydrous nine-coordinate compl...
