Practical Syntheses of N-Substituted 3-Hydroxyazetidines and 4-Hydroxypiperidines by Hydroxylation with Sphingomonas sp. HXN-200
摘要:
[GRAPHICS]Hydroxylation of N-substituted azetidines 11 and 12 and piperidines 15-19 with Sphingomonas sp. HXN-200 gave 91-98% of the corresponding 3-hydroxyazetidines 13 and 14 and 4-hydroxypiperidines 20-24, respectively, with high activity and excellent regioselectivity. High yields and high product concentrations (2 g/L) were achieved with frozen/thawed cells as biocatalyst. For the first time, rehydrated lyophilized cells were successfully used for the biohydroxylation.
Novel substituted piperidines of the general formulae (I) and (II) with the substituent definitions as explained in detail in the description are described. The compounds are suitable in particular as renin inhibitors and are highly potent.

The present invention relates to tetrahydropyridine derivatives of formula (1) which may be therapeutically useful as anti-bacterial agents, more particularly FabI inhibitors.
in which X, Y, Z and “n” have the same meanings given in the specification, and pharmaceutically acceptable salts and pharmaceutically acceptable stereoisomers thereof that are useful in the treatment and prevention in diseases or disorder, in particular their use in diseases or disorder where there is an advantage in inhibiting Enoyl-ACP reductase enzyme (FabI) activity.
The present invention also provides methods for synthesizing and administering the FabI inhibitory compounds. The present invention also provides pharmaceutical formulations comprising at least one of the FabI inhibitory compounds together with a pharmaceutically acceptable carrier, diluent or excipient therefor.
