The synthesis of the Fmoc-protected C-glycosyl tyrosines 1 and 2, together with two other related C-glycosyl tyrosines, has been achieved. Key reactions involved (i) the reaction of a glycal with an organozinc reagent (carrying an aryl iodide functio

The barriers to interconversion of the stereomers of a number of N-cyano-O-phenylisoureas and related systems have been examined by variable temperature 1H NMR spectroscope. Rate constants were determined from the coalescence temperature using the Gu

Hydrogenolysis of the benzyl ester 5 gave the imidazolone 6 rather than the desired acid 1, and the related benzyl ester 11 also hydrogenolysed to the imidazolone 12. Examination of the hydrolysis of simpler guanidine derivatives with trifluoroacetic

The reaction of hydrazine with suitably substituted isoureas gives tetraazabicyclo[3.3.0]octanes. The products obtained in this reaction are extremely susceptible to the nature of the substrate and the reaction conditions, but a suitable combination

The preference for 5- over 6-membered rings in the intramolecular cyclisation of amines with diesters can be partially overcome with mixed methyl (or benzyl), tert -butyl diesters, and this effect is enhanced where there is a β-substituent. The hexa
