, p. 2554 - 2558 (2019/04/30)
A promiscuous lipase-catalyzed carbon-phosphorus bond formation is presented. The developed enzymatic Pudovik-Abramov reaction of various aromatic and aliphatic aldehydes with dialkyl phosphonates provides biologically and pharmacologically relevant α-hyd
α-ketophosphonates as ester surrogates: Isothiourea-catalyzed asymmetric diester and lactone synthesis
Smith, Siobhan R.,Leckie, Stuart M.,Holmes, Reuben,Douglas, James,Fallan, Charlene,Shapland, Peter,Pryde, David,Slawin, Alexandra M. Z.,Smith, Andrew D.
