Journal ArticleDOI
A facile Lewis acid-promoted allylation of azetidin-2-ones
TL;DR: In this article, exposure of 3α-chloro-3-phenylthioazetidin-2-ones and allyltrimethylsilane to a Lewis acid promotes a remarkably facile and stereoselective C-3 allylation to give 3αallyl-3.
Journal ArticleDOI
Lewis acid mediated functionalization of β-lactams: mechanistic study and synthesis of C-3 unsymmetrically disubstituted azetidin-2-ones
TL;DR: A convenient and efficient route to novel unsymmetrically disubstituted azetidin-2-ones is described.
Journal ArticleDOI
A new synthetic approach for novel C-3 substituted β-lactams
TL;DR: The stereospecificity of the formation of mono-substituted products may be rationalised on the basis of the SnCl 4 mediated intermediate complex A that reacts via an S N 2 mechanism.
Journal ArticleDOI
A Convenient Synthesis of Esters of 6-Aminopenicillanic Acid
Journal ArticleDOI
Facile synthesis of (Z)- and (E)-3-allylidene-β-lactams via thermal β-elimination of trans-3-allyl-3-sulfinyl-β-lactams
TL;DR: In this article, a competent synthetic route for the synthesis of novel (Z )- and (E )-3-allylidene-β-lactams is described.
