Question:

(a) A mixture of (R)-2,3-dihydroxypropanal (D-glyceraldehyde) and 1,3-dihydroxyacetone that is treated with aqueous NaOH rapidly yields a mixture of three sugars: D-fructose, D-sorbose, and racemic dendroketose (only one enantiomer is shown here). Explain this result by means of a detailed mechanism. 

(b) The same product mixture is also obtained if either the aldehyde or the ketone alone is treated with base. Explain. 

CH,OH O- НОСН- -ОН ČH,OH Dendroketose
