(19R)-1-Acetyl-17,19-epoxycuran

One of the Strychnos alkaloids, this base is found in S. psilosperma and yields colourless crystals from MeOH. It has [α]²²_D + 88° and gives a picrate as yellow needles from MeOH, m.p. l73-5°C and a methiodide, M.p. 30l-3°C. The methoperchlorate begins to decompose at 250°C and the N-oxide, which forms colourless crystals from Me2CO, has m.p. 241-3°C.
