HY Zeolite: An Efficient, Heterogeneous and Recyclable Catalyst for the One Pot Synthesis of α-Aminophosphonates

Mira JA, Nisar AD, Khuroob MA and Tomara R

An eco-friendly and efficient three-component protocol was developed for the one-pot synthesis of α-amino phosphonates from aldehydes, amines and trialkyl phosphates at room temperature using H-form zeolites as heterogeneous catalyst. The method is general with wide substrate scope giving products in excellent yields under mild reaction condition. The catalyst exhibits an excellent catalytic performance with good recyclability. The reusability and simple work up procedure make the protocol more attractive and eco-friendly.
