Aldolases are powerful biocatalysts for the stereoselective formation of carbon–carbon bonds and are widely used in the synthesis of chiral intermediates for pharmaceutical applications. Among them, 2-deoxyribose-5-phosphate aldolase (DERA) has been extensively exploited for the preparation of the conserved side chain of statins. In this work, we report a novel chemoenzymatic approach for the synthesis of nucleobase-substituted lactol products as potential precursors of new statin analogues. A C49M variant of DERA from Pectobacterium atrosepticum (PaDERA C49M) was employed to catalyze sequential aldol additions using aldehyde-functionalized nucleobases as non-natural electrophilic substrates. The formation of nucleobase-containing lactols was confirmed, demonstrating for the first time the acceptance of nucleobase-derived aldehydes in DERA-catalyzed aldol reactions. This strategy provides access to structurally novel statin side-chain precursors and expands the synthetic potential of DERA toward the generation of new classes of bioactive compounds.

La asignatura Química Orgánica II se dicta en la Facultad de Ciencias Exactas para distintas carreras. Es una materia del quinto cuatrimestre, se encuentra luego de un ciclo de formación básica de dos años. Es una de las materias básicas más importantes para estas carreras, ya que sus contenidos se centran en el estudio de las estructuras y de la reactividad de las moléculas bioorgánicas. A pesar de ser una asignatura de suma importancia, debido principalmente a sus contenidos, sus trabajos prácticos de laboratorio presentan algunas deficiencias. Estos problemas se relacionan con su organización teórica, conceptual, didáctica y también, con su puesta en práctica. En este sentido realizamos un diagnóstico de la situación y llevamos a cabo una propuesta de innovación con un formato de “Taller de Práctica Experimental en Síntesis Orgánica”. Este taller se propone como la unidad de reemplazo, en el programa de la asignatura, de las actuales prácticas de laboratorio. Se busca generar una propuesta superadora mediante la incorporación de un espacio de práctica de excelencia, trabajo individual y reflexión; pretendiendo aportar a la formación profesional en consistencia con el perfil de egresado propio de las carreras que incluyen a la asignatura.
