Use of metal complexation in the synthesis of medium-ring acetylenic lactones
Najdi, Samir D.,Olmstead, Marilyn M.,Schore, Neil E.
, p. 335 - 358 (1992)
The hexacarbonyldicobalt complexes of several appropriately designed acetylenic lactone precursors have been prepared, and lactones containing Co2(CO)6-complexed triple bonds in seven-, ten-, and eleven-membered rings obtained.The latter were best obtaine
Preparation of Medium-Ring Acetylenic Lactones Utilizing Metal-Promoted Alkyne Bending
Schore, Neil E.,Najdi, Samir D.
, p. 5296 - 5298 (2007/10/02)
Reaction of a variety of acetylenic hydroxycarbonyl compounds with Co2(CO)8 gives rise to readily isolated alkyne-Co2(CO)6 complexes in which lactonization, previously impossible due to geometric constraints, proceeds relatively smoothly due to "bending"
