    • For example, essentially the same result (0.5 h, 98%, α/β=11/89) was obtained in the glycosylation of 3 with 1-octanol (cf. entry 8 in Table 2) by using the recovered catalyst which was dried at 200°C in vacuo for 22 h before use. For the reusability of lanthanoid(III) triflates as catalysts, see also references 4b–4d.
