Organocatalysis by bimacrocyclic NHCs: Unexpected formation of a cyclic hemiacetal instead of a γ-butyrolactone
Winkelmann, Ole,Naether, Christian,Luening, Ulrich
, p. 553 - 556 (2009)
Two bimacrocyclic imidazolinium salts of different size, precursors to respective NHCs (N-heterocyclic carbenes), were tested as precatalysts in the reaction of aromatic aldehydes or ketones with enals. The expected lactones were produced in most cases, b
