Herein we report a selective DIBAL-H-mediated reduction of a heterocyclic diester to the corresponding monoaldehyde using continuous flow chemistry. The use of continuous flow enabled operation at lower temperatures and better control of the reaction time, thereby allowing for a significant increase in reaction selectivity and yield compared with batch conditions. The reaction's development as a continuous flow process and its scale-up from laboratory gram scale to multikilogram scale are discussed, including design of experiments studies to probe the optimal reaction window.

A selective oxygenation of picolines and their derivatives has been achieved by usingasimple copper salt as a catalyst and molecular oxygen as an oxidant, where the α-position of the alkyl substituent is selectively oxidized to give the corresponding aldehydes or ketones. Addition of a catalytic amount of water enhances the catalytic activity, which could be attributed to the role of the proton donor to activate the substrates.
