Abstract:
The first total synthesis of the dihydrobenzofuran neolignan quiquesetinerviusin A and its related structure have been described. Phenolic coupling is the key step to constructing the dihydrobenzofuran skeleton with vanillin as the raw material. The hydroxyl group was protected with dihydropyran (DHP) and the ester group was reduced with diisobutylaluminium hydride (DIBAL-H) in order to obtain the crucial intermediate diol, which was then condensed with an acid ligand to give the desired compounds following removal of the protecting groups.

Abstract:
Sodium tetraisopropylcyclopentadienide (2) is attacked selectively in 5-position by tosyl azide with formation of 5-diazo-1,2,3,4-tetraisopropylcyclopentadiene (1) and also by the iminium salt [Me2NC(H)OMe]+ MeOSO3- to yield 1,2,3,4-tetraisopropyl-6-dimethylamino-pentafulvene (3) with concomitant methanol elimination. In a one pot reaction 3 adds methyllithium to form a cyclopentadienide intermediate (4) which is converted in situ to 1,2,3,4- tetraisopropyl-6-methyl-pentafulvene (5) with dimethylchlorosilane. By the same procedure with 1,4-dilithiobutane instead of methyllithium two tetraisoproylfulvene moieties are linked to the bis-fulvene 8 with a -(CH2)4- backbone. 3 can be converted directly to 1,2,3,4- tetraisopropylpentafulvene (7) with diisobutylaluminum hydride. 5 again adds methyllithium to give lithium pentaisopropylcyclopentadienide (6) or can be deprotonated at the 6-methyl group with potassium hydride. The intermediate potassium salt gives 1,2,3,4-tetraisopropyl- 6-trimethylsilylmethyl-pentafulvene (9) with trimethylchlorosilane. The fulvene 7 could be η6-coordinated to the tricarbonyl chromium complex 10 with [Cr(CO)3(NCEt)3], 5 and 7 yield the molybdenum analogues 11 and 12 with [Mo(CO)3(NCEt)3].
