The hydrolytickineticresolution (HKR) of terminal epoxides catalyzed by chiral (salen)Co(III) complex 1 x OAc affords both recovered unreacted epoxide and 1,2-diol product in highly enantioenriched form. As such, the HKR provides general access to useful, highly enantioenriched chiral building blocks that are otherwise difficult to access, from inexpensive racemic materials. The reaction has several

has been developed for synthesis of oligonucleotides containing N1-adducted 2'-deoxyinosines. The 2'-deoxyinosine adduct of 3,4-epoxy-1-butene was prepared from (+/-)-4-acetoxy-3-bromo-1-butene and tetraisopropyldisiloxanediyl-protected 2'-deoxyinosine with base. The 2'-deoxyinosine derivative was then incorporated into the oligodeoxynucleotide sequence 5'-d(CGGACXAGAAG)-3' (X = N1-(1-hydroxy-3-bu

lipophilic tail conveyed aerobicactivity. Incorporation of a 2-position oxygen atom into a rigid 5-nitroimidazooxazine provided the first 5-nitroimidazole with aerobicactivity. Across both series, anaerobic and aerobicactivities were not correlated and Mtb mutants lacking the deazaflavin-dependent nitroreductase (Ddn) retained anaerobic sensitivity to some compounds. Aerobicactivity appears to be correlated
The concise nature and modularity of the synthesis described for deguelin and tephrosin (retrosynthetic analysis depicted) should facilitate access to labeled analogues to dissect the mechanism of action of this important pharmacophore.
