Alkylation of the substituted cycloalkanones 14a–d and 30 with (Z)-1-bromo-4-methyl-3-trimethylstannyl-2-pentene (13) produced compounds 15a–d and 33, which were readily converted into the correspo...
The structures of amijitrienol and 14-deoxyisoamijiol, two newditerpenoids isolated from the brownseaweed Dictyota linearis, have been established as 1 and 2 on the basis of spectral and chemical evidence.
