nucleophilic aromatic subsitution (SNAr) reactions between various nucleophiles and electrophiles. The mild reactionconditions facilitate a broad functional group tolerance that can be utilized for subsequent derivatization for the synthesis of pharmaceutically relevant building blocks. The use of only equimolar amounts of all reagents and water as reaction solvent reveals the greenness and sustainability

organic synthesis in recyclable water. This includes homogeneouscatalysis (including examples employing only ppm levels of catalyst), heterogeneous catalysis, and biocatalytic transformations, including a multistep chemoenzymatic sequence. Use of Savie frequently leads to significantly higher yields than do conventional surfactants, while obviating the need for waste-generating organic solvents.
Savie 是一种可生物降解的表面活性剂,源自维生素 E 和聚肌氨酸 (PSar),开发用于可循环水中的有机合成。这包括均相催化(包括仅使用 ppm 级催化剂的例子)、多相催化和生物催化转化,包括多步化学酶序列。使用 Savie 通常会比传统表面活性剂产生显着更高的产率,同时无需使用产生废物的有机溶剂。
