The reaction of isocyanomethylenetriphenylphosphorane, generated in situ from the corresponding phosphonium salt, with a diverse set of aldehydes afforded vinyl isocyanides in good to high yields. Excellent E-selectivity was observed for aliphatic aldehydes and 2,6-disubstituted aromatic aldehydes, whereas Z-olefins were formed predominantly with ortho-substituted aryl aldehydes. (Z)-1-Bromo-2-(2-isocyanovinyl)benzene (5l) was found to be a truly universal isonitrile since, after Ugi reaction, the resulting secondary amide unit (RNHCO-) is convertible under both acidic and basic conditions. The application of 5l in the synthesis of polyheterocycles is also illustrated.

Page/Page column 5, (2008/06/13)
The present invention provides a process for the preparation of imidazoles by reacting a cyano compound with a silylalkylisocyanide compound. Such imidazoles are useful pharmacologically-active compounds and/or intermediates for the preparation of pharmacologically-active compounds.

Trimethylsilylmethyl isocyanide is prepared by a new method which gives a higher overall yield and circumvents the use of methyl isocyanide.
Alkaloid synthesis via the intramolecular imidate methylide 1,3-dipolar cycloaddition reaction

A concise synthesis for the neurotoxic physostigmine alkaloid d,l-eserethole is described which relys upon an intramolecular cycloaddition reaction involving a "non-stabilized" imidate methylide and an unactivated alkene. The facility of this cyclization
The Direct Generation of N-Acyl Formimidate Methylides. An Efficient Approach to the Synthesis of Pyrrolidine Derivatives
Livinghouse, Tom,Smith, Richard
, p. 210 - 211 (2007/10/02)
The reaction of silyl-formamidines and silyl-thioformimidates with acyl fluorides gives N-acyl imidate methylides which have been successfully trapped with several dipolarophiles to afford pyrrolidine derivatives in high yields.
