A NEWS SYNTHESIS OF SPIROACETALS VIA ALKYLIDENATION OF ESTER CARBONYLS WITH METAL CARBANE COMPLEXES
Mortimore, Michael,Kocienski, Philip
, p. 3357 - 3360 (1988)
Metal carbene complexes prepared from alkoxy-substitued 1,1-dibromalkanes react with alkoxy-substitued esters to give enol ether intermediates which undergo acid-catalysed methanolysis and cyclisation to spiroacetals in good overall yield.

Zweifel olefination is a catalyst-free reaction that serves alkene functionalization. While most methods employ commercially available boron pinacol esters, we have assembled a sequence in which the two partners of the formal coupling reaction are installed successively, starting from inexpensive boron alkoxides. The in situ formation of bisorganoborinates was accomplished by consecutive reaction of two different organometallic species. This single-pot procedure represents a great advancement in the generation of organoborinates and their involvement in C-C bond formation.
An olefin metathesis/double bond isomerization sequence catalyzed by an in situ generated ruthenium hydride species
Schmidt, Bernd
, p. 816 - 819 (2007/10/03)
The direct conversion of allyl ethers to cyclic enol ethers using an olefin metathesis/double bond migration sequence is described. Ruthenium carbene complexes were activated to catalyze the double bond migration step by addition of hydride sources, such
