Cyclopentanoid allysilanes in synthesis: Generation via intramolecular ene reaction of activated 1,6-dienes and application to the synthesis of functionalized diquinanes
A new general route to -1,2-disubstituted cyclopentanoid allylsilanes useful in di-and triquinane synthesis is described based on intramolecular enereaction of activated 1,6-dienes featuring a homoallylsilane unit as the ene donor.
A new general route to cis-1,2-disubstituted cyclopentanoid allylsilanes is described based on intramolecular enereaction of activated 1,6-dienes featuring a homoallylsilane unit as the ene donor. In addition, application of these allylsilanes to the synthesis of some di- and triquinanes including the fungal metabolite (±)- hirsutene is presented.
