Highly congested, axially chiral 1,8-bisphenolnaphthalenes have been synthesized in 75% overall yield by palladium-catalyzed Suzuki coupling of 1,8-diiodonaphthalene and 4-methoxy-2-methylphenylboronic acid followed by regioselective formylation and

The condensation between stereolabile 1,8-bis(3′-formyl-4′-hydroxyphenyl)naphthalene, 1, and two amino acid molecules results in the formation of chiral diimines exhibiting strong CD signals. This reaction has been used to develop a chiroptical s

A stereodynamic, axially chiral triaryl probe is locked into a single conformation upon condensation with two amino alcohol substrates. The well-defined chiral amplification in the diimines formed results in intense Cotton effects at high wavelengths

Essential oils isolated from the aerial parts of two different Lebanese wild populations of Dittrichia graveolens were analyzed by GC and GC/MS. It was shown that around 90% of the total composition consisted of oxygenated compounds. The four major c
