Three approaches to the enantioselective synthesis of 3-amino-4-substituted-2-azetidinones by condensation of α-amino ester enolates with imines are described: (i) application of chiral ester derivatives of N,N-diethylglycine; (ii) application of chiral N

The enantioselective synthesis of trans-(3R,4S)-1-(R)-α-methylbenzyl-3-(2,2,5,5-tetramethyl-1-aza-2,5-disilacyclopentyl)-4-N-(R)-α-methylbenzyliminoazetidin-2-one has been accomplished by reaction of the chlorozinc enolate of an N,N-diprotected glycine ethyl ester with a chiral α-diimine.
