One-pot reductive amination and Suzuki-Miyaura cross-coupling of formyl aryl and heteroaryl MIDA boronates in array format.

Formyl-substituted aryl and heteroaryl MIDA boronates were prepared by a DMSO-free method and used in the first reported one-pot reductive amination-Suzuki-Miyaura cross-coupling sequence. This sequence was then carried out in parallel array format, using microwave-assisted in situ release cross-coupling of MIDA boronates to generate a library with diversity along two axes, affording rapid and convenient access to an array of druglike molecules.
