Martzel, Thomas,Lohier, Jean-Fran?ois,Gaumont, Annie-Claude,Brière, Jean-Fran?ois,Perrio, Stéphane
, p. 96 - 106 (2017)
The efficient sulfinate-catalyzed intermolecular addition reaction of α-substituted allenyl sulfones and allenoates with Michael acceptors is highlighted. The sequence proceeds under mild conditions to provide a scalable and efficient access to versatile
Phosphine-catalyzed annulations of azomethine imines: Allene-dependent [3 + 2], [3 + 3], [4 + 3], and [3 + 2 + 3] pathways

In this paper we describe the phosphine-catalyzed [3 + 2], [3 + 3], [4 + 3], and [3 + 2 + 3] annulations of azomethine imines and allenoates. These processes mark the first use of azomethine imines in nucleophilic phosphine catalysis, producing dinitrogen

A convenient, high yield, two step synthesis of 3-allylcoumarins and their benzo derivatives is described from 2-hydroxybenzaldehydes.The benzaldehydes (2a-j) on reaction with phosphorane 3 provide E-ethyl-α-allylcinnamates (4a-j) in high yields.These est
