an extremely efficient catalyst for the synthesis of α-aminophosphonates. A three-component reaction (3-CR) of an amine, an aldehyde or a ketone, and a di-/trialkyl phosphite (Kabachnik−Fields reaction) took place in one pot under solvent-free conditions to afford the corresponding α-aminophosphonates in high yields and short times. The use of solvent retards the rate of the reaction and requires a
A novel and ef?cient synthetic route to α‐aminophosphonates containing benzothiazole moiety via a cascade three‐component reaction from conveniently available starting materials has been developed. The target compounds 3a–3g, 7 and 8a, 8b were evaluated for their anticancer activities against the cancer cell line HL‐60 in vitro by the MTT method. Compound 3g showed good cancer inhibitory activity against
