Rhodiumcatalyst mediated hydroformylation of glucal derivatives has been achieved for the first time in good yields and selectivies using [Rh2µ-S(CH2)3NMe2}2(cycloocta-1,5-diene)2] and tris(ortho-tert-butylphenyl) phosphite as auxiliaryligand giving, principally, 2-formyl derivatives.

The hydroformylation of glycals was achieved using Rh(I)(acac)(CO)2 catalyst. For glucals, the C-2 formyl pyran was the major product whilst for galactal an equimolar mixture of the C-2 and C-1 regioisomers were observed.
