Remarkable effects of lone pair-lone pair interactions on the extremely stereoselective [2 + 2] cycloaddition of azidoketene to chiral 3-imino-b-lactams: Remarkable effects of lone pair-lone pair interactions on the extremely stereoselective [2 + 2] cycloaddition of azidoketene to chiral 3-imino-b-lactams. Ojima, Iwao; Nakahashi, Kazuaki; Brandstadter, Stephan M.; Hatanaka, Naoto (Dep. Chem., State Univ. New York, Stony Brook, NY 11794, USA). J. Am. 107010-89-9 is the cas registry number. This chemical is also mentioned in this article. Chem. Soc., 109(6), 1798-805 (English) 1987. CODEN: JACSAT. ISSN: 0002-7863. DOCUMENT TYPE: Journal CA Section: 34 (Amino Acids, Peptides, and Proteins) Section cross-reference(s): 27 b-Lactams I-IV underwent stereoselective [2 + 2] cycloaddn. reactions with azidoketene to give the corresponding azido bis-b-lactams, e.g. I gave bis-b-lactam V. The reactions of I, II, and III proceeded with >99.5% stereoselectivity, whereas the reaction of IV gave bis-b-lactam VI with 62% d.e. The above cycloaddn. reaction of iminoazetidine VII gave bis-azetidine VIII with 32% d.e. inducing the asymmetry in the opposite direction. In addn. to the conventional steric effects, the lone pair-lone pair interaction of b-lactam oxygen with the intermediate betaine oxygen is the crucial factor for the stereoselective [2 + 2] cycloaddn. of azidoketene to I, II, and III. Possible mechanisms are proposed. V was hydrogenated to give the corresponding amino deriv., which was N-acetylated and then cleaved by hydrogenolysis to give tripeptide Ac-(S)-Phe-(R)-Phe-(S)-Ala-OCMe3. .

Syntheses and antibacterial activity of some new N-(3-methyl-2-quinoxaloyl) amino alcohols and amine 1,4-dioxides: Syntheses and antibacterial activity of some new N-(3-methyl-2-quinoxaloyl) amino alcohols and amine 1,4-dioxides. Sabri, Salim S.; El-Abadelah, Mustafa M.; Owais, Wajih M. (Fac. Sci., Jordan Univ., Amman, Jordan). J. Chem. Eng. Data, 29(2), 229-31 (English) 1984. CODEN: JCEAAX. ISSN: 0021-9568. DOCUMENT TYPE: Journal CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) The syntheses and the in vitro and in vivo antibacterial activities of a series of N-(3-methyl-2-quinoxaloyl) amino alcs. and amine 1,4-dioxides, and their deoxygenated analogs are described.There are some commonly used reagents with their cas registry numbers 7533-40-6 and 480-96-6 in this article. The quinoxaline 1,4-dioxide deriv. of the naturally occurring (-)-ephedrine I was the most potent antibacterial agent of the series. The presence of a hydroxy group and a tertiary amide appears to be assocd. with enhancement of the antibacterial action. .
