A continuous flow system for the multiparameter (flow rate, temperature, residence time, stoichiometry) optimization of the DIBALH reduction of esters to aldehydes is described. Incorporating an in-line quench (MeOH), these transformations are generally complete in fewer than 60 s. Mixing

A systematic investigation of the reductive ring-expansion reaction of cyclic ketoximes fused to aromatic rings with diisobutylaluminum hydride (DIBALH) is described. This reaction regioselectively afforded a variety of five- to eight-membered bicyclic heterocycles or tricyclic heterocycles containing nitrogen neighboring an

An optimized protocol for the DIBALH reductive acetylation of acyclic esters and diesters is described. This reductive acetylation procedure allows a wide variety of esters to be converted into the corresponding alpha-acetoxy ethers in good to excellent yields. It was

The reaction of DIBALH with bis(heteroannulated)-pyranosides containing the perhydrofuro[2,3-b]pyran moiety is described. The hydride attack at the anomeric carbon (C-9a) resulted in the exclusive tetrahydrofuran ring opening. The selectivity of this reaction has been evaluated as other benzylidene acetals built

Reaction of purine nucleosides, such as 2',3'-isopropylideneinosine (1a) and 2',3'-isopropylideneadenosine (1c), with diisobutylaluminum hydride (DIBAL) in dry tetrahydrofurane resulted in the formation of the corresponding 9-(2',3'-isopropylideneribity)purines (2) in good yields. Oxidation of the ribityl derivatives (2) with NalO4 and subsequent
