Moriarty, Robert M.,Kim, Joonggon,Brumer, Harry
, p. 51 - 54 (1995)
The enyne needed for coupling to a CD-ring fragment, namely, 3S,5R-oct-1-en-7-yne-3,5-diol, in the Trost-Dumas carbopalladation route to 1α,25-dihydroxyvitamin D3 was synthesized from D-xylose in 13 steps and 21percent yield.
Synthesis of two novel chiral building blocks for anti- And syn-1,3-diols
Wu, Yong,Guan, Mei

Two novel chiral building blocks 1 and 2 for anti- and syn-1,3-diols have been synthesized starting from the readily available and inexpensive D-(+)-xylose.
Preparation of 3-Deoxy-aldonolactones by Hydrogenolysis of Acetylated Aldonolactones

Acetylated aldono-1,4-lactones, when treated with hydrogen in the presence of triethylamine and palladium on carbon, form acetylated 3-deoxy-aldono-1,4-lactones in high yield through elimination of the 3-acetoxy group and subsequent stereospecific hydrogenation of the unsaturated intermediate.Thus, acetylated D-galactono-1,4-lactone (1) yields tri-O-acetyl-3-deoxy-D-xylo-hexono-1,4-lactone (3a).Acetylated D-mannono- or D-glucono-1,4-lactone both give 3-deoxy-D-arabino-hexono-1,4-lactone (10a), whereas the four acetylated D-pentono-1,4-lactones (14-17) all afford di-O-acetyl-D-threo-pentono-1,4-lactone (18a).D-Gluconolactone can be converted into (R)-γ-caprolactone (27) on treatment with hydrogen bromide followed by a series of reductions.Similarly, D-lyxonolactone produces 2,3-dideoxy-D-glycero-pentono-1,4-lactone (29).
