2MgCl afforded 6-O-acetyl-2,3,4-tri-O-benzyl-1-C-phenyl-α- D-glucopyranose (11d) and 6-O-acetyl-1-C-benzyl-2,3,4-tri-O-benzyl-α-D- glucopyranose (11e) in 89% and 82% yields, respectively, with almost no production of the deacetylated compounds. It seemed that these bulky organometallic reagents were apt to produce the nucleophilic attack on the conformationally fixed carbonyl group at C-1 of 10 rather than on the acetyl group at C-6. The treatment of 11b-e using NaOMe in MeOH quantitatively afforded 1b-e. 2,3,4-Tri-O-benzyl-1-C-methyl-α-D-mannopyranose (6a) was similarly prepared in 82% yield from 6-O-acetyl-2,3,4-tri-O-benzyl-D-manno-1,5-lactone(13) . Preparation of 9 and 12 was reported in the following literature. See: (a) Koto, S.; Morishima, N.; Takenaka, K.; Kanemitsu, K.; Shimoura, N.; Kase, M.; Kojiro, S.; Nakamura, T.; Kawase, T.; Zen, S.

4, the solvent was evaporated under reduced pressure. The crude product was purified by preparative silica gel TLC (EtOAc-hexane = 1:2) to give 2a (45 mg, 93%).
