note

Dondoni (reference 2) has reported the condensation of the aldehyde 4c (ee = 84%) with 2-(trimethylsilyl)-thiazole, which proceeds with no loss of optical purity, so we believe that it is the conditions of our condensation reaction which result in racemisation.

3) to the corresponding tert-butyl ester 12b for comparison with a known compound, see reference 4 above. A small amount of the corresponding trans-oxazolidinone 12a, which could not be separated by chromatography, was always present, so direct comparison of specific rotation with the literature value could not be made. equation presented

It is interesting to note that an isomerisation in the opposite sense has been observed in the preparation of Taxotere® using an isopropylidene protected derivative of anti-phenylisoserine: Denis, J.-N.; Kanazawa, A.M.; Greene, A.E. Tetrahedron Lett. 1994, 35, 105. See also reference 10 above.

note
-
Both diastereoisomers of closely related esters, in contrast to the thioesters which we have prepared, are reported in reference 11 above to be stable to silica gel chromatography. It therefore appears that the thioester group is responsible for the observed isomerisation to the cis-oxazolidinones.
