Über die Kondensation cyclischer Hexene mit Phenol. (Ein Beitrag zur chemischen Struktur des Lignins.)

Abstract: Unlangst hat der eine von uns an Hand formulierter Vorstellungen die genetischen Zusammenhange entwickelt, die zwischen den lkxosen, als den ersten Assimilationsprodukten der Pflanze, und der Kohle, nls ihrem letzten hochmolekularen Umwandlungsipmdukt, bestehenl). Als Zwischenstufc in diesem groBen UmwandlungslprozeB sieht er die Uildung eines Kondensationsproduktes vor, das, in Form der Hauptbestandteile des I, i gn i n s teilweise schon in der Pflanze selbst vorgebildet, sowohl den C h ar a k t e r e i n e s… Show more

“…These two reactions are simultaneous as evidenced by ' H n.m.r. monitoring of the reaction of (1) with methanol, 2,2-dimethylpropan-1-01 (15), propan-2-01 and 3P-cholestanol (22). In each case, the two derivatives appeared simultaneously: methanol gave anisole (67%) and methyl trifluoroacetate (33;/,) after 2.25 h, propan-2-01 gave the phenyl ether (45%) and the trifluoroacetate (55%) after 4 h, and 2,2-dimethylpropan-1-01 (15) gave the phenyl ether (16) (62"/,) and the trifluoroacetate (17) (38%) after 25 h. 3P-Cholestanol aqueous NaOH, the mixtures of phenyl ethers and alcohols were easily resolved.…”
