DENSELY FUNCTIONALIZED CYCLOPENTENONES
Tius, Marcus A.,Zhou, Xiao-ming
, p. 4629 - 4632 (1989)
The cationic cyclopentannelation reaction tolerates alkyl substitution both on the allene ether fragment as well as on the terminus of the enone fragment.The densely functionalized cyclopentenone products are models for marine prostanoid synthesis.
