Vinyl thiazoles are converted to saturated aldehydes due to the olefin reduction that takes place in the course of the thiazolyl-to-formyl deblocking sequence. See: A. Dondoni, G. Fantin, M. Fogagnolo, A. Medici, P. Pedrini, Tetrahedron 1988, 44, 2021.

The facile anomerization of 15 as well as of 11a and 12a, or their products, is very likely due to acid catalysis by silica gel or traces of acetic acid contained in acetonitrile. This enhanced reactivity at the anomeric center is typical of 2-deoxy sugars. See: P. M. Collins, R. J. Ferrier, Monosaccharides, Wiley, New York, 1995, pp. 73 and 217.
