2. The building block 1 was obtained from glucose diacetonide in nine steps with an overall yield of 42%, (Pg=Bn7), or 34% (Pg=MOM8). The building block 2 was more tedious to obtain, and was prepared in 11 steps with 28% overall yield (methyl ester, Pg=Bn9) from a 3-C-methyl-d-glucoside which was obtained from d-glucose in 40% overall yield,10 or in 19 steps from glucose diacetonide in 11% overall yield (ethyl ester, Pg=Bn).11 Mixtures of E- and Z-isomers were always obtained.
