“…It is worth noting that control experiments using each catalytic component at a time showed that the triple action of the hybrid catalyst, hydroquinone, and air are required The co-immobilization of Pd and lipase in cavities of MCF as described by Bäckvall [169] has also been reported by Magadum and Yadav [170,171]. For instance, a CAL-B/Pd hybrid catalyst was employed in a one-pot two steps reduction/kinetic resolution cascade to give enantiopure (R)-phenyl ethyl acetate from acetophenone (Scheme 2) [170]. The co-immobilization of Pd and lipase in cavities of MCF as described by Bäckvall [169] has also been reported by Magadum and Yadav [170,171].…”

“…The method for co-immobilization of metal and enzyme into MCF introduced by Bäckvall [170] has also proven useful to produce a laccase/Pd hybrid catalyst [172]. Laccases are copper enzymes that can oxidize compounds under mild conditions employing molecular oxygen as an oxidizing agent to give water as a byproduct.…”

Multicatalytic Hybrid Materials for Biocatalytic and Chemoenzymatic Cascades—Strategies for Multicatalyst (Enzyme) Co-Immobilization

During recent decades, the use of enzymes or chemoenzymatic cascades for organic chemistry has gained much importance in fundamental and industrial research. Moreover, several enzymatic and chemoenzymatic reactions have also served in green and sustainable manufacturing processes especially in fine chemicals, pharmaceutical, and flavor/fragrance industries. Unfortunately, only a few processes have been applied at industrial scale because of the low stabilities of enzymes along with the problematic processes of their recovery and reuse. Immobilization and co-immobilization offer an ideal solution to these problems. This review gives an overview of all the pathways for enzyme immobilization and their use in integrated enzymatic and chemoenzymatic processes in cascade or in a one-pot concomitant execution. We place emphasis on the factors that must be considered to understand the process of immobilization. A better understanding of this fundamental process is an essential tool not only in the choice of the best route of immobilization but also in the understanding of their catalytic activity.

“…In a study done by the Yadav group, siliceous foam was used to incorporate enzymes and palladium nanoparticles together in a tandem system. 90 This system was designed to convert acetophenone to 1-phenylethyl acetate through a phenyl-ethanol intermediate. However, recyclability was limited with the mesocellular foam, and a selectivity of only 49.1% was achieved.…”

Tandem Catalytic Systems Integrating Biocatalysts and Inorganic Catalysts Using Functionalized Porous Materials

Tandem catalysis research has recently come alive with various methods to design biosynthetic pathways utilizing enzymes and inorganic catalysts in single-pot systems. Clever applications of porous supports have brought about ways for the successful integration of incompatible enzymes and inorganic catalysts into these onepot systems to enhance the properties of the combined catalysts. Over the past several years research in this area has shown that supports can be used to stabilize catalysts as well as act as active components within the systems. In this Perspective, we present and discuss current reports that demonstrate successful combinations of enzymes and inorganic catalysts supported on porous supports for tandem reactions and challenges yet to be overcome.
