ON THE MECHANISM OF THE LEWIS ACID CATALYZED CYCLOCONDENSTION OF ALDEHYDES WITH SILOXYDIENES
Larson, Eric R.,Danishefsky, Samuel
, p. 1975 - 1978 (1982)
Competing cycloaddition versus aldolization-cyclization processes are demonstrated in the formation of 6-styryl-5,6-dihydro-γ-pyrone via the BF3 catalyzed reaction of cinnamaldehyde with trans-1-methoxy 3-trimethylsilyloxy-1,3-butadiene.
