Koo, BonSuk,McDonald, Frank E.
, p. 1737 - 1740 (2008/02/02)
The tungsten-catalyzed cycloisomerization of alkynyl alcohols can be conducted without using photochemistry, using a stable tungsten Fischer carbene as the precatalyst for this transformation. A variety of alkynyl alcohols undergo cycloisomerization under
Synthesis of seven-membered ring glycals via endo-selective alkynol cycloisomerization
Alcázar, Eva,Pletcher, Joseph M.,McDonald, Frank E.
, p. 3877 - 3880 (2007/10/03)
Alkynyldiols 1 undergo cycloisomerization to the corresponding seven-membered cyclic enol ethers 2 under tungsten carbonyl catalysis. This novel transformation proceeds with good yields and virtually complete regioselectivity for all diastereomers of 1, f
