A qualitative and semi-quantitative method was established for the investigation of low-molecular-weight volatile carbonyl compounds in cigarette whole smoke. The carbonyls were trapped on a silica gel "column" and eluted with water. The aqueous solution was then treated with benzyloxyamine
Forty-three oxime derivatives were synthesized by allowing O-benzylhydroxylamines to react with primary benzaldehydes or salicylaldehydes; these products were gauged as potential inhibitors of β-ketoacyl-(acyl-carrier-protein) synthase III (FabH). Among the 43 compounds, 38 are reported herein for the first time. These
[reaction: see text]. The 1,4-addition of O-benzylhydroxylamine to alpha,beta-unsaturated imide 1 in the presence of BF3.Et2O proceeds with the preferential attack of the nucleophile on the Cbeta-re face. To explain this unexpected reactivity 1H, 13C, and 11B NMR investigations have

A highly regioselective and traceless solid-phase route to 1,7,8-trisubstituted purines has been developed. This methodology could be extended to the preparation of 8-azapurines and [i]-condensed purines. A representative set of 17 purines, azapurines, and [i]-condensed purines was synthesized. This paper
