title: 4,5,6-Tri-O-acetyl-2,3-di-S-ethyl-2,3-dithio-d-allose diethyl dithio-acetal.
abstract: The title compound, C(20)H(36)O(6)S(4), was obtained by ethanethiol-ysis of 3,5,6-tri-O-acetyl-1,2-O-isopropyl-idene-α-d-gluco-furan--ose. One of the ethyl groups is disordered over two sites with refined occupancies of 0.869 (6) and 0.131 (6). Compared with the precursor, the absolute configuration of the stereocenters at positions C-3 and C-2 are inverted and maintained, respectively.
