By using solvent‐free and heat conditions, the Petasis boronic Mannich reaction of salicylaldehydes with various boronic acids and secondary amines without catalyst is described. The alkylaminophenols were obtained in moderate to good yields in a shorter reaction time than the traditional methods.
On the basis of our recently reported aniline aqueous borylation, molecular diversity was achieved in a one-pot process by combining other reactions such as esterification, Suzuki-Miyaura coupling, hydrogenolysis, or Petasis borono-Mannich.

this work, efficient, mild, and eco-friendly procedure of 1-aminoalkyl-2-phenol/Betti base from one-pot three-component condensations of aldehyde, phenol, and morpholine in the presence of sulfated polyborate catalyst, under a solvent-free condition at 100 °C, is described. The key advantages of the present method are short reaction time, high yields, aqueous work-up procedure, low cost, stable, reusable
