Triplet Energy Transfer‐Driven Intermolecular [2+2] Photocycloaddition of Acyclic Imines and Indoles: Facile Access to Azetidine‐Fused Indolines

Advanced Science, EarlyView.
An intermolecular aza‐Paternò‐Büchi reaction of indoles and acyclic imines is enabled by visible‐light‐driven triplet energy transfer, providing azetidine‐fused indolines up to 93% yield for 30 examples and providing a novel protocol to access previously inaccessible scaffolds. ABSTRACT Currently, successful examples of the aza‐[2+2] photocycloaddition

Hybridization of Homogeneous and Heterogeneous Catalysis to Develop a Novel Biocatalyst via Immobilization of Lipase on Surface Modified Mesoporous Silica Towards Biodiesel Synthesis Application

Advanced Energy and Sustainability Research, EarlyView.
The 3‐(methacryloyloxy)propyltrimethoxysilane surface functionalized SBA‐15 (MP‐SBA‐15) is used for the first time as a lipase carrier. The immobilized CAL‐B exhibits high thermal stability and superior catalytic activity. CAL‐B/SBA‐15 suggests that optimum hydrophobicity gives better catalytic activity.
