A. Parallel synthesis of 96 alkylamines via an APBM method, with 4 aldehydes, 4 amines and 6 alkylboron reagents as the coupling partners. B. Reaction plate design and results of a 96-well plate screening. Regarding how each building block was sorted in a 96-well plate manner, see Supplementary Information section 'Alkylamine library syntheses' for details. C. Display of representative reaction products that were purified and characterized.
