A new synthesis of 4-(2,3,6-trimethylphenyl)butan-2-ol, a C13-norisoprenoid artifact from Vitis vinifera linn. and its conversion to several terpenic natural products of plant and marine origin

The four-step synthesis of 4-(2,3,6-trimethylphenyl)butan-2-ol (1), starts from 5,8-dimethyl-3,4-dihydro-2-naphthaldehyde (2).The trimethyldihydronaphthalene (10) obtained from the reduction of 2 is ozonised to the keto aldehyde (11), which is reduced to

PREPARATION DE CETONES ET D'ALCOOLS INSATURES A PARTIR DE LA METHYLVINYLCETONE. UNE SYNTHESE SIMPLE ET EFFICACE D'ALCOOLS ISOPRENIQUES

The preparation of olefinic ketones and alcohols by means of a retro Diels-Alder reaction is described.This process has been applied to high yield syntheses of linalool 6e, nerolidol 6f and the sesquiterpene alcohol 10 recently isolated from the alga Laurencia nidifica.

A Short Synthesis of 3-Methyl-5-(2,3,6-trimethylphenyl)-1-penten-2-ol, a Sesquiterpene Isolated from Laurencia Nidifaca

The racemic sesquiterpenoid alcohol 7 was synthesized in four steps (27percent overall yield) from the cyclohexadienone 1.The key steps are the regioselective addition of the pentadienyllithium 2 to 1 and Lewis-acid induced aromatization 4 -> 6.

Laurencia sesquiterpene biogenetic-type interconversions

Several aromatic sesquiterpenes from Laurencia algae were prepared from chamigrene skeleton precursors. Chemical evidence was adduced to support a biogenetic-type scheme for the synthesis of perforenol and perforene. By means of x ray analysis the structure and absolute configuration of one of the intermediates was established.
