Abstract
The structure of vitamin K2, m. p. 54°, is established as 2‐methyl‐3‐all‐trans‐farnesylgeranylgeranyl‐1,4‐naphtoquinone by total synthesis and comparison of the synthetic compound with vitamin K2 from putrefied fish meal. It contains a terpenoid side chain of an odd number of seven isoprene units with 7×5 = 35 C‐atoms. In addition, a second vitamin K factor isolated from putrefied fish meal, m. p. 50°, is identified as 2‐methyl‐3‐all‐trans farnesylfarnesyl‐1,4‐naphtoquinone by comparison with a synthetic sample. Moreover eight other compounds of the vitamin K2 series have been synthesized.This publication has 8 references indexed in Scilit:
