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.

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.

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.
