چکیده
synthesis of some new monocyclic β-lactams containing a quaternary carbon center via a [2+2]cycloaddition reaction is described. the reaction of achiral diphenyl ketene with chiral aldimines derivedfrom chiral 2, 3, 4, 6-tetra-o-acetyl-β-d-galactopyranosylamine, 2, 3, 4, 6-tetra-o-acetyl-β-dglucopyranosylamine and different benzaldehydes resulted in the formation of β-lactams as singlediastereomers.

synthesis of some new polycyclic aromatic monocyclic β-lactams
in this paper the synthesis of some new polyaromatic monocyclic β-lactams has been reported. these cycloadducts have been synthesized by the [2+2] ketene-imine cycloaddition reaction known as the staudinger reaction. all of the products have been fully characterized by ir, 1h-nmr, 13c-nmr, mass spectroscopy and elemental analyses. the x-ray crystal structure of a cis β-lactam has been also pres...
متن کاملSynthesis and antimicrobial activity of some new sugar-based monocyclic beta-lactams.
The syntheses of some new sugar-based monocyclic beta-lactams possessing several other functionalities in addition to the carbohydrate moiety are described. The key step was the Staudinger [2+2] cycloaddition of chiral carbohydrate Schiff base 5 with phthalimidoacetyl chloride to yield the sugar-based monocyclic beta-lactam 6 as a single isomer. Treatment of protected beta-lactams 6 and 8 with ...
متن کاملSynthetic Approaches toward Monocyclic 3‐Amino‐β‐lactams
Due to the emerging resistance against classical β-lactam-based antibiotics, a growing number of bacterial infections has become harder to treat. This alarming tendency necessitates continued research on novel antibacterial agents. Many classes of β-lactam antibiotics are characterized by the presence of the 3-aminoazetidin-2-one core, which resembles the natural substrate of the target penicil...

The studies on design and synthesis of new monocyclic β-lactam esters 4(R/S)-(1'-methoxycarbonylpropyl2'(R/S)-thio)-3(R)-phenylacetamidoazetidin-2-one (3a) and 4(R/S)-(1'-methoxycarbonyl-2'-methyl-propyl-2'thio)-3(R)-phenylacetamidoazetidin-2-one (3b) were described. Compounds 3a and 3b were specifically designed to retain all penicillin substructures except the bicyclic system, which would be ...
متن کاملSynthesis of substituted [3]dendralenes and their unique cycloaddition reactions.
Dimethylsulfonium methylide mediated olefination of 2-phenylethenylidene phosphonoacetate followed by the Horner-Wadsworth-Emmons reaction with aromatic aldehydes provided access to reactive 1,5-diaryl-2-ethoxycarbonyl [3]dendralenes which in situ underwent Diels-Alder cyclodimerisation leading to highly functionalised cyclohexenes with very high regio- and stereoselectivity.
متن کاملAsymmetric synthesis of anticancer β-lactams via Staudinger reaction.
This study describes the symmetric synthesis of novel β-lactams derived from chrysene directed towards their SAR, as well as their biological activities against several cancer cell lines in vitro. To our knowledge, this is the first report on the synthesis and biological evaluation of optically active anticancer β-lactams. That these anticancer effects are not uniform against all tumor lines su...
