5-Cyano-7-carboxylic acid can be synthesized by reaction of the diketone of formula VI with a weak aqueous base such as sodium acetate or sodium bicarbonate followed by separation of the resulting residue The obtained compound is preferably 5-β-cyano-11-α 17-dihydroxy-3-oxo-17α-pregnan-7α 21-dicarboxylic acid γ-lactone

Triethyl orthoformate is an organic compound with the formula HC(OC 2 H 5) 3 It is a colorless volatile liquid It is orthoester of formic acid It is commercially available The industrial synthesis is from hydrogen cyanide and ethanol It may also be prepared from the reaction of sodium ethoxide and chloroform: CHCl 3 + 3 Na + + 3 EtO-→ HC(OEt) 3 + 3 ⁄ 2 H 2 + 3 NaCl Triethyl

One synthesis of quinolones begins with the formation of an ethyl ethoxymethylenemalonate as seen in this Organic Syntheses paper I've been asked if the malonate derivative would be formed if methylmalonate was treated with trimethyl orthoformate with a catalytic amount of $mat{H^+}$ without heating The nature of the solvent isn't mentioned but I guess the reaction is carried out in

Sodium ethoxide (Sodium ethylate) is a sodium alkoxide It has been synthesized by reacting sodium with ethanol It undergoes decomposition in the presence of water to afford ethanol and sodium hydroxide It is widely employed as a strong base in organic synthesis studies Packaging 5 100 500 g in steel can Safety Documentation Safety Information Personal Protective Equipment Eyeshields
