The C-C bond cleavage of terminal and internal diynes takes place readily in the presence of catalytic amounts of Ru3(CO)12 or Pd(NO3)2 and of 2-aminophenol, giving the corresponding benzoxazoles and ketones in good to high yields. Thus, reaction of 2-H2NC6H4OH with RCCCCH [R = hexyl, decyl, cyclohexyl, Me3C, PhCH2CH2, (Me2CH)3SiO(CH2)4, Cl(CH2)3] in MeOH containing Ru3(CO)12 and NH4PF6 gave mixtures of 2-methylbenzoxazole and the C-2 substituted benzoxazoles I in 58-98% yields in addition to acetone and RCOMe. The substituted aminophenols II (R1 = 4-NO2, 4-Cl, 4-Me, 4-MeO, 5-NO2, 5-Me, 3-Me) reacted similarly with 1,3-decadiyne to give methylbenzoxazoles III and hexylbenzoxazoles IV. The two different modes of bond cleavage in these reactions are cleavage of an alkyne C-C triple bond and cleavage of the C-C single bond between the two alkyne groups. In the experiment, the researchers used many compounds, for example, 2,5-Dimethylbenzoxazole (cas: 5676-58-4Recommanded Product: 5676-58-4).
2,5-Dimethylbenzoxazole (cas: 5676-58-4) belongs to benzoxazole derivatives. Benzoxazoles belong to the group of well-known antifungal agents with antioxidant, antiallergic, antitumoral and antiparasitic activity. Benzoxazoles are prominent in medicinal chemistry due to their wide spectrum of pharmacological activities such as antiparkinson, inhibition of hepatitis C virus, 5-HT3 antagonistic effect.Recommanded Product: 5676-58-4
