Direct and Efficient Synthesis of β-L-Rhamnopyranosides
Iversen, Tommy,Bundle, David R.
, p. 5389 - 5393 (2007/10/02)
Methyl α-L-rhamnopyranoside (1) was converted in a single-stage procedure to crystalline methyl 4-O-benzoyl-2,3-O-cyclohexylidene-α-L-rhamnopyranoside (2).This compound served as a stable derivative from which 4-O-benzoyl-2,3-O-cyclohexylidene-α-L-rhamnop
