A simple and efficient method has been developed for the selective oxidative esterification of aldehydes using commercially available Amberlyst-15 as a catalyst. H2O2 released from a clathrate structured 4Na2SO4·2H2O2·NaCl oxidant serves as an efficient source of terminal oxidants. Various aromatic, heteroaromatic, and aliphatic aldehydes undergo selective esterification to give good to excellent yield. The heterogeneous catalyst, Amberlyst-15, exhibits high reactivity and can be recycled over several runs. The 4Na2SO4·2H2O2·NaCl oxidant was found to be superior to commonly used oxidizing agents providing an anhydrous, easy to handle and stable form of H2O2

A general, catalytic and sustainable synthesis of amides has been targeted which utilises a chemoenzymatic step to generate an activated amide coupling partner in situ. A screen of a series of known activating agents was performed and the successful agents taken forward to determine their utility in such a one-pot enzyme-catalysed process. In these studies, a new chemoselective reagent ((isopropylideneamino) 2-phenylacetate) has been identified, which demonstrates excellent selectivity for the acylation of primary anilines over secondary anilines, unlike the more conventional acid chloride equivalent, which is unselective. The development of a chemoenzymatic synthesis of 2-hydroxyethyl benzoates (ethylene glycol mono-benzoate esters) has also been achieved.
