Although analyses of tephra-derived glass shards have been undertaken in New Zealand for nearly four decades (pioneered by Paul Froggatt), our study is the first to systematically develop a formal, comprehensive, open-access reference dataset of glas

1,3:2,4-di-O-isopropylidene-L-ribitol and related compounds

Autor: B. H. Rees, J.M. Webber, A.B. Foster, F.E. Hardy, K. W. Buck

Publikováno v: Carbohydrate Research. 2:115-121

Acetonation of ribitol (catalysed by mineral or Lewis acids) affords a 1,2:4,5-and a 1,2,3,4-di-O-isopropylidene derivative. Evidence is presented which indicates that the latter isomer has a 1,3:2,4-distribution of the ketal rings.

Aspects of stereochemistry. Part XXIV. The acid-catalysed rearrangement of 2,4-O-benzylidene-D-erythrose and 2,3-O-benzylidene-erythritol

Autor: A. B. Foster, K. W. Buck, B. H. Rees, N. Baggett, J. M. Webber

Publikováno v: Journal of the Chemical Society C: Organic. :212

On treatment with toluene-p-sulphonic acid in dimethylformamide, 2,4-O-benzylidene-D-erythrose rearranges to 2,3-O-benzylidene-D-erythrofuranose with the phenyl group endo. The structure assigned to the rearranged product is proved, and a mechanism i
