  (Phosp)hole in one: A palladium‐catalyzed synthesis for directly assembling phosphole skeletons from triarylphosphines through CH and CP bond cleavage was developed. This approach overcomes several of the limitations of the so far reported methods. Phospholes bearing a range of functionalities (including Br, F, CO2Me, Ac, and CN) and an array of fused rings (naphthalenes, anthracenes, furans, and

  Process for the preparation of tetrahydropterin and tetrahydropterin derivatives by hydrogenating pterin and pterin derivatives with hydrogen in the presence of a hydrogenating catalyst, in which the hydrogenation is carried out in a polar reaction medium and metal complexes that are soluble in the reaction medium are employed as the hydrogenation catalysts. The process is suited to the hydrogenation, particularly asymmetric hydrogenation, of folic acid, folio acid salts, folio acid esters, folio acid ester salts or dihydroforms thereof, with the proviso that in the event of using folic acid, carboxylic acid salts thereof or dihydroforms thereof the reaction medium is aqueous, and in the event of using folic acid esters, folic acid ester salts or dihydroforms thereof the reaction medium is an alcohol. The process opens up straightforward access to achiral and chiral pterin derivatives.

  通过在存在氢化催化剂的情况下，用氢气氢化葉酸和葉酸衍生物制备四氢生物葉酸和四氢生物葉酸衍生物的过程，其中氢化是在极性反应介质中进行的，并且可溶于反应介质的金属配合物被用作氢化催化剂。该过程适用于葉酸、葉酸盐、葉酸酯、葉酸酯盐或其二氢形式的氢化，特别是不对称氢化，但若使用葉酸、其羧酸盐或二氢形式，则反应介质为水，若使用葉酸酯、葉酸酯盐或其二氢形式，则反应介质为醇。该过程为得到无手性和手性葉酸衍生物提供了直接途径。
