The Carbenoid Approach to Peptide Synthesis

Autor: Diane Mary Coe, Paul A. Clarke, Richard T. Buck, Neil D. Pearson, Leigh Ferris, Martin James Drysdale, David Haigh, Elizabeth Swann, Christopher J. Moody

Publikováno v: Chemistry - A European Journal. 6:2160-2167

A different approach to the synthesis of dipeptides is described based on the formation of the NHCHR1CONH-CHR2CO bond by carbenoid N-H insertion, rather than the formation of the peptide bond itself. Thus decomposition of triethyl diazophosphonoaceta

Synthesis of functionalised oxazoles and bis-oxazoles 1

Autor: Richard T. Buck, Christopher J. Moody, Mark C. Bagley, S. Lucy Hind

Publikováno v: Journal of the Chemical Society, Perkin Transactions 1. :591-600

A new method for the synthesis of oxazoles, and in particular chiral non-racemic oxazoles derived from amino acids, has been developed. Thus, rhodium(II) catalysed reaction of diazocarbonyl compounds 6 and 11 in the presence of amides 8 and 10 result

Publikováno v: Tetrahedron Letters. 37:7631-7634

Decomposition of methyl 2-diazophenylacetate in the presence of dimethylphenylsilane and a chiral dirhodium(II) catalyst results in SiH insertion of the intermediate carbenoid with varying degrees of enantioselectivity (up to 47% ee).
