The present invention relates to a process for thermolytic fragmentation of a sugar into a composition comprising C.sub.1-C.sub.3 oxygenates. In particular, it relates to the use of heat carrying particles providing improved yields of C.sub.1-C.sub.3 oxygenates and improved fluidization characteristics making it suitable for industrial scale production of e.g. glycolaldehyde. It also regards a circulating fluidized bed system comprising the heat carrying particles.

Provided is a process for producing an optically active hydroxyaldehyde or aminohydroxyaldehyde. The process for producing an optically active hydroxyaldehyde or aminohydroxyaldehyde is characterized by reacting an aldehyde or an imine with a boric acid enol ester in the presence of a copper compound and an optically active bidentate phosphine compound.
