halogen on the adjacent carbon, were condensed with (2,2-diphenylhydrazono)acetic acid (2); the resulting esters undergo radical cyclization to afford carbohydrates fused to a 2,2-diphenylhydrazino lactone unit (6c,d-13c,d). In suitable cases (9c,d) such carbohydrate lactones can be elaborated into C-glycosyl amino acids.
