TLC analysis of the products by aldol condensation. (A) DRP synthesis. Lane 1, DRP standard; lane 2, reaction mixture with DERAEco; lane 3, reaction mixture with DERAPae; lane 4, reaction mixture with DERATma. (B) Sequential aldol reaction with acetaldehyde. Lane 1, reaction mixture with DERAEco; lane 2, reaction mixture with DERAPae; lane 3, reaction mixture with DERATma. The product was identified as 2,4,6-trideoxy-d-erythro-hexapyranoside, using 1H NMR, as described in Materials and Methods.
