Modelos estereoquímicos de adição à carbonila
Química NovaThe stereochemical control in the generation of new stereogenic centers is of paramount importance in organic chemistry. In this context, diastereoselective additions to carbonyl compounds bearing a stereogenic center at the α-position are of particular ...

Advanced Synthesis &Catalysis, Volume 368, Issue 8, 15 April 2026.Achieving selective aldol reactions using dienolates as nucleophiles is challenging due to the potential formation of up to eight different regioisomeric and stereoisomeric aldol adducts. This study demonstrates that Ge dienolates can facilitate highly diastereoselective aldol reactions. Furthermore, the key role of the solvents is also clarified.
