An efficient protocol for stereoselective construction of densely functionalized pyrrolidines by a [3+2]-annulation reaction of N-tosyl-alpha-amino aldehydes and 1,3-bis(silyl)propenes is described. This methodology is also applied as a key step in the synthesis of the polyhydroxylated pyrrolidine alkaloid 2,5-dideoxy-2,5-imino-D-glucitol (DGDP)

A novel synthetic protocol for Lewis acid-promoted addition of 1,3-bis(silyl)propenes to N-phenyl glyoxylamide and ethyl glyoxylate is developed. The reaction does not appear to be influenced by the steric bulk of the 1,3-bis(silyl)propenes, and represents a new approach to vinylation of glyoxylates; the products are obtained in good yields.
