“…[1,2] For instance, the tertiary aacetylenic alcohols 2-phenylbut-3-yn-1-ol (1a) and 1,1,1-trifluoro-2-phenylbut-1-yn-3-ol (2a) were recently applied for the synthesis of A 2A receptor antagonists that were shown to be orally active in a mouse catalepsy model. [3] In addition, fluorine-containing optically active alcohols are also of great interest due to their potential use as ferroelectric liquid crystals and drugs. [4] Carboxylester hydrolases (lipases, EC 3.1.1.3, esterases, EC 3.1.1.1) represent a class of versatile biocatalysts for the preparation of enantiopure compounds, especially of optically pure secondary alcohols and to a smaller extent also for the resolution of primary alcohols and carboxylic acids.…”

“…[5] Optisch aktive tertiäre Alkohole sind wichtige Bausteine für die organische Synthese [6] und wurden kürzlich zur Herstellung eines oral aktiven A 2A -Rezeptorantagonisten in einem Maus-Katalepsiemodell verwendet. [7] Darüber hinaus sind fluorierte optisch aktive Alkohole von großem Interesse, da sie in ferroelektrischen Flüssigkristallen und Wirkstoffen Verwendung finden können. [8] Auf der Basis einer vorangegangenen Studie zum rationalen Proteindesign [5a] berichten wir hier über die Strategie einer fokussierten gerichteten Evolution zur Inversion der Enantioselektivität der Esterase BS2 gegen acetylierte tertiäre Alkohole (Schema 1).…”

“…[153][154][155][156][157] Several isosteres of the triazolo-triazine nucleus have been synthesized; in particular some oxazolo-pyrimidines (68) [158] and triazolo-pyrazines (69,70). [159,160] All these compounds showed good potency at the A 2A AR and good selectivity versus A 1 AR, in particular derivative 69, but all these com- www.chemmedchem.org pounds have not been fully characterized at the four AR subtypes. Some purine derivatives recently reported by several groups seem to be very promising.…”
