Synthesis of phenolic natural products

Chaly, Thomas. January 1984 (has links)
A new method for the acetalization of carbonyl compounds using chlorotrimethylsilane under mild conditions is described. Carbonyl compounds are acetalized by ethylene glycol with chlorotrimethylsilane. / Two isomeric methyl olivetolates were synthesised by the condensation of 1,3-bis(trimethylsiloxy)-1-methoxybutadiene with the corresponding electrophilic components. This reaction has clearly indicated the discriminative behaviour of 1,3-bis(trimethylsiloxy)-1-methoxybutadiene towards different electrophilic sites thus leading to regio-selectivity. / A new method for the synthesis of olivetol is described. This method provides a shorter route to olivetol from acyclic precursors. / A new synthesis of (DELTA)('1)-tetrahydrocannabinol is described. The synthesis is patterned after biogenetic considerations. / A new method for the synthesis of poly (beta)-carbonyl compounds using diketene and enol silyl ethers is described. / The possibility of synthesising gossypol by the cyclo-aromatization procedure was investigated.
