Bridgehead enolates and bridgehead alkenes in a welwistatin model series
Boissel, Valerie,Simpkins, Nigel S.,Bhalay, Gurdip,Blake, Alexander J.,Lewis, William
, p. 1398 - 1400 (2009)
Bridgehead metallation is possible in a ketone having the welwistatin skeleton, and this facilitates installation of the isothiocyanate function present in the natural product, and also enables synthesis of remarkable bridgehead alkenes.
