Procedure:
A 250-ml 2-necked round-bottomed flask was equipped with a magnetic stirring bar, a thermometer and an argon inlet. To a mixture of 30.00 g of methyl 3-oxovalerate (0.225 mol) and 125 ml of methyl orthoformate (121.1 g, 1.12 mol) was added under stirring 7.5 g of amberlist 15. The reaction was slightly exothermal at beginning and the temperature reached 31° C. A check with Drager test tube indicated the development of carbon monoxide. The suspension was stirred at rt for 3 h and then filtered into a 500-ml 4-necked pear-shaped flask equipped with an oil bath, a thermometer, an argon inlet, a 20-cm Vigreux column with a distillation head, a vacuum pump with vacuum controller and a cold trap. The volatile components of the reaction mixture were removed by distillation at a still temperature between 37 and 48° C. and a pressure between 250 and 40 mbar. The head temperature reached max 30° C. The residue, 31.3 g Methyl (E)-3-methoxy-2-pentenoate as a yellow oil was used without purification in the next step (theor. amount 32.5 g calculated as enol ether).

Procedure:
The compound (II) can be prepared by a similar process to the process for preparing 1',2'-diacetyl-L-biopterin [Bernard Schircks, Jost H. Bieri and Max Viscontini, Helvetica Chimica Acta, 60(1), 211 (1977)]. According to the process, L-rhamnose hydrate is reacted with ethanethiol. The obtained L-rhamnose-diethylmer-captal is converted to 5-deoxy-L-arabinose through 1,1-diethylsulfonyl-L-rhamnose. 5-Deoxy-L-arabinose is reacted with phenylhydrazine to obtain 5-deoxy-L-arabinose-phenylhydrazone. 5-Deoxy-L-arabinose-phenyl-hydrazone is reacted with an acylating agent. The obtained 2,3,4-triacyl-5-deoxy-L-arabinose-phenylhyrazone is reacted with 2,4,5-triamino-6-hydroxy-pyrimidine dihydrochloride, and then oxidized with an oxidizing agent such as iodine to obtain a 1',2'-diacyl-L-biopterin. L-Biopterin can be obtained by deacylation of the 1',2'-diacyl-L-biopterin.

Procedure:
A solution of 651 mg (3.597 mmol) of 5-chlorothiophene-2-carbonyl chloride in 10 ml of anhydrous tetrahydrofuran is added to a solution of 1.89 g (3.597 mmol) of the product from Example 3A and 1.25 ml of diisopropylethylamine (Hünig-Base) in 40 ml of anhydrous tetrahydrofuran. The reaction mixture is stirred at room temperature for 15 hours. The solvent is then removed on a rotary evaporator, and the residue is taken up in dichloromethane and washed successively with saturated sodium bicarbonate solution and water. After drying over anhydrous sodium sulphate, the mixture is filtered, evaporated and the residue is purified by preparative HPLC (Method 7). This gives 1.05 g (43% of theory) of the title compound.
