Oh Dear, falling back onto your Appeal to Authority fallacy?
Now here's a fascinating bit:
General procedure for the preparative synthesis of cytidine nucleosides by hydrolysis
of anhydronucleosides as exemplified by the synthesis of α-D-ribocytidine 36
D-Ribofuranosyl-2,2'-anhydrocytidine hydrochloride 35 (500 mg, 1.91 mmol) was
dissolved in H2O (10 mL), and Dowex® 100 × 8 HO–-form anion-exchange resin (2
g) was added. The resultant suspension was stirred for 4 h whilst monitoring UV
absorbance. On completion of reaction, the suspension was filtered, and the filtrate
lyophilised to give α-D-ribocytidine 36 (460 mg, 98%) as a white powder.
More Dowex, this time an anionic type. Where would anionic resins come from on the PreBiotic Earth?
Don't try the Zeolite excuse here, as they are cationic.
