摘要：

The addition of 2-lithiobenzothiazole to D-gluconolactone followed by deoxygenation of the resulting ketose affords a mixture of benzothiazolyl alpha- and beta-D-glucopyranoside; treatment of this mixture with sodium methoxide gives the beta-anomer from which the title aldehyde is obtained in a pure form by transformation of the benzothiazole ring into the formyl group.
