Reagents and Synthetic Methods. Part 58. Synthesis of β-Lactams from Acetic Acids and Imines promoted by Vilsmeier Type Reagents

The development of a practical method for the stereospecific preparation of several 3-substituted β-lactams from acetic acids and imines is described.The key step of the method is the activation of the carboxy component by means of Vilsmeier type reagents.The preparation of some N-(2'-hydroxyethyl)-β-lactams and N-(p-dimethyl-t-butylsiloxyphenyl)-β-lactams as intermediates for N-H azetidinones is also reported.For the last compounds the steric bulk of the N-substituent is the key feature for a high cis-β-lactam formation.
