Glycosyl triflates with a 2,3-oxazolidinone protecting group were generated from thioglycosides by low-temperature electrochemical oxidation. The glycosyl triflates reacted with alcohols to give the corresponding glycosides β-selectively at low temperatures. However, α-selectivity was observed in the absence of base at elevated reaction temperatures. In situ generated triflic acid promotes the ...

An application of readily available hydrazides in the Petasis 3-component coupling reaction is presented. An investigation of the substrate scope was performed to establish a general, synthetically useful protocol for the formation of hydrazido alcohols, which were selectively converted to oxazolidinone and oxadiazolone ring systems through triphosgene-mediated cyclization reactions.

The SPME (Solid Phase Microextraction) analysis of the scent H. hircinum showed presence elemicin in a relevant amount eugenol. sample adriaticum collected Abruzzo 4-amino-5-(4-morpholinylmethyl)-2-oxazolidinone, ?-ocimene, decyl decanoate, and 9-tricosene as main components. at Marsico Nuovo has an aroma where component was pentadecyl hexanoate, 9-tricosene, methyleugenol, tetradecane, pentade...

(+)-(2R,3R)-7-Formyl-6-methoxy-2-methoxymethyl-3- (3,4-methylenedioxyphenyl)-2,3-dihydro-1,4-benzodioxin (2), a key building block for the total synthesis of haedoxan A, was synthesized from (4R)-4-(phenylmethyl)-2-oxazolidinone (3) in ten steps with a 12% overall yield.

Methicillin-resistant Staphylococcus aureus clonal lineage ST398 and methicillin-susceptible lineage ST9 strains have their main reservoir in swine but can colonize and cause infections in humans. The phenicol/lincosamide/oxazolidinone/pleuromutilin/streptogramin A multidrug resistance gene cfr was detected in isolates of both clonal lineages, rendering a spread to humans with exposure to swine...

Vancomycin has been a predominant treatment for methicillin-resistant Staphylococcus aureus (MRSA) infections for decades. However, growing reservations about its efficacy led to an urgent need for new antibiotics effective against MRSA and other drug-resistant Staphylococcus aureus strains. This review covers three new anti-MRSA antibiotics that have been recently approved by the FDA: dalbavan...

Methicillin-resistant Staphylococcus aureus (MRSA), including community-associated and hospital-associated strains, is a major cause of human morbidity and mortality. Treatment options have become limited due to the emergence of MRSA strains with decreased sensitivity to vancomycin, which has long been the first-line therapy for serious infections. This has prompted the search for novel antibio...

Linezolid (LZD), severed as the first oxazolidinone antibiotic, was active against multidrug-resistant gram-positive strains. LZD can induce thrombocytopenia, anemia and leukocytopenia. Currently, reports on pure red cell aplasia (PRCA) cases induced by LZD are relatively rare (4-7). In this paper, we reported a patient with PRCA twice induced by LZD. A 37-year-old man was diagnosed with myelody...

OBJECTIVES Linezolid is an oxazolidinone antibiotic used in the treatment of infections caused by vancomycin-resistant enterococci. Resistance to linezolid has been associated with a G2576U mutation in domain V of the 23S rRNA. PATIENT AND METHODS We present clinical details and susceptibility data from multiple Enterococcus faecium strains isolated from a liver transplant patient over 13 mon...
