Facile synthesis of 2-C-methyl-D-arabino-γ-1,4-lactones and mechanism study

In our previous research on the synthesis of 3,5-di-O-benzoyl-2-C-methyl-D-arabino-γ-lactone 4a, the reaction mechanism of DMSO-mediated configuration inversion of C2 hydroxyl group in the lactone was ambiguous. As a follow-up to this research, we used s

A NEW SYMTHESIS OF 2-C-METHYL-D-RIBONO-1,4-LACTONE AND THE C-9/C-13 FRAGMENT OF METHYNOLIDE

The synthesis of the glucosaccharino lactone, 2-C-methyl-D-ribono-1,4-lactone 7 from 2,3-O-isopropylidene-D-glyceraldehyde 1 is reported.Lactone 7 was transformed into (2R,3R)-2,3-dihydroxy-2-methylpentanoic acid 18 (the C-9/C-13 fragment of Methynolid) b
