โœฆ Synopsis

Recently, Segal and Taube reported 1) that the 16-OH configuration of quillaic acid(g should be revised from o( to g on the basis of the diacetonide(2) formation of its tetraol derivative

(2) and as a result suggested that the 16-OH configuration of the following 12 d -oleanene tri-* Blank colmm: not measured due to less solubility, or uuclear due to overlapping. ** These lowest methyl eignals might be due to 8p-CH3 rather than 140(+X3.
