  • atoms with hydroxy groups (singlets at 1.22 and 1.48 ppm, 3 H each, and 1.44 ppm, 6 H) and of a Ar-O-CH2--CH--grouping (multiplet at 4.20-4.51 ppm, 3 H). These facts agree completely with the structure of oxypeucedanin hydrate acetonide, as was confirmed by the results of the treatment of (I) with a mixture of acetic and hydrochloric acids in a ratio 3:1. This led to the formation of oxypeucedanln hydrate (II), C,6H,606, mp 132-133°C and of isooxypeucedanin (III), C,6H,~05, with mp 145-146°C… CONTINUE READING
