New classes of antibacterial oxazolidinones with C-5, methylene O-Linked heterocyclic side chains
摘要:
Exploration of the structure-activity relationships of the traditional C-5 acetamidomethyl side chain of the oxazolidonone antibacterials has yielded new, potent series of compounds of which the first examples, the O-linked iosoxazoles are described in detail, leading to the selection of the pre-clinical candidate AZD2563.

inherent double controlled strategy of sterically hindered propargyl alcohols without the installing of external directing groups. Its synthetic robustness and practicality have been illustrated by the concise synthesis of bervastatin, a hypolipidemic drug, and late‐stage modification of complex alkynes with precise regioselectivity.

N-Acylbenzotriazoles react with arylisocyanates to form, depending on the type of acyl group, compounds based on five different classes of polycyclic heteroaromatics. Higher alkanoyl-, acetyl-, acetoacetyl-, aroyl-, and cinnamoylbenzotriazoles yield, respectively, derivatives of quinoline, pyrimidino[5,4-c]quinoline, benzo[b]-1,8-naphthyridine, phenanthridine, and indolo[2, 3-b]quinoline by incorporating

resulting from the development of a catalyzed reaction of ketenes (or their derived zwitterionic enolates) and imines. The products of these asymmetric reactions can serve as precursors to a number of enzyme inhibitors and drug candidates as well as valuable synthetic intermediates. We present a detailed study of the mechanism of the beta-lactam forming reaction with proton sponge as the stoichiometric
