We report an eco-friendly, easy and efficient methodology for the synthesis of α-aminophosphonates using [Ce(l-Pro)]2(Oxa) as a catalyst.

PPL, chymosin and BSA as efficient biocatalysts (low catalyst loading, high yields) in an eco-friendly synthesis of N,S-acetals.

A simple, efficient and green chemical ultrasound assisted thio-Michael addition reaction between thiols and (Z)-azlactones aiming non-natural amino acid derivatives using chiral Zn[(l)-Pro]2as a heterogeneous catalyst is herein described.

Herein we present a new, highly efficient (60‐ 98 %), low cost and easy procedure for the addition of thiols to N‐Boc imines catalyzed by [Zn(L‐Pro)2] aiming the construction of some different N,S‐acetals by using a low catalytic loading (1 % mol) in short reactions time and under mild conditions.

An efficient method has been developed for the preparation of α-aminophosphonates by using zinc di(L-prolinate) as a catalyst under mild reaction conditions. The method has the advantages of high yields, short reaction times, and easy workup conditions.
