Michael acceptors vinyl phosphonates

The vinyl phosphonates act as Michael acceptors of phosphonate ions (20). The soft P atom of the latter species is utilized for the bond formation. [Pg.106]

Other Michael Acceptors, other Michael acceptors such as malei-mides [27], vinyl phosphonates [28], alkylidine malonates [29], ethyl 2-(dithox-yphosphoryl)acrylate [30], a-keto-a,(3-unsaturated esters [31], -Y-keto a, 3-unsaturated esters [32], and a,(3-unsaturated thiol esters [33] were also applicable in the enantioselective Michael reactions with aldehydes (Scheme 5.15). [Pg.156]
