Negative-ion mode ESI/MS spectra of oligomerization reaction.

(a) The oligosaccharide mixture of unprotected and partially protected galactopyranosyl residues comprise compounds 12‴ (AD, see Scheme 1 for definition of A, B and D), 13 (AAD), 14 (ABD), 15 (AAAD), 16 (ABBD), 17 (AAAAD) that are observed as their chloride adducts. (b) Fractionation of the reaction mixture (c) Oligosaccharide mixture after deprotection: dimer (12), trimer (AAA) and tetramer (AAAA) are observed as their chloride adducts.
