On June 15, 2018, Peer Mohamed, Shahul Hameed; Bharatham, Nagakumar; Katagihallimath, Nainesh; Sharma, Sreevalli; Nandishaiah, Radha; Ramachandran, Vasanthi published a patent.COA of Formula: C4H7NO3 The title of the patent was Preparation of heterocyclic derivatives for use as antibacterial agents. And the patent contained the following:
Title compounds I [R1 = (un)substituted alkyl, alkenyl, cycloalkyl, etc.; R2 and R3 independently = H, F, OH, alkyl, etc.; R8 = H, F, or alkyl; R9 = H, F, CN, OH, or alkyl; L = N, CH, CCN, C-halo, etc.; M = CH or alkyl; each X and Y independently = N, CH, CCN, etc.; Z = O, S, or CH2; m = 0 or 1; n = 0 to 2; with provisions], and their stereoisomers, pharmaceutically acceptable salts, complexes, hydrates, solvates, tautomers, polymorphs, racemic mixtures, optically active forms and pharmaceutically active derivatives thereof, are prepared and disclosed as antibacterial agents. Thus, e.g., II was prepared by a multistep procedure (preparation given). I were evaluated in S. aureus (ATCC 29213) antibacterial activity assays, e.g., II demonstrated a <4 μg/mL min. inhibitory concentration in LB media. The experimental process involved the reaction of (R)-5-(Hydroxymethyl)oxazolidin-2-one(cas: 97859-49-9).COA of Formula: C4H7NO3
