“…Baker (6) endeavored to obtain substances still conforming to the estradiol pattern but with its hydronaphthalene skeleton ruptured at places other than in hexestrol. Among these compounds, written according to Baker, (12,206,207) at first followed similar lines and synthesized l-(m-hydroxyphenyl)-3-(p-hydroxyphenyl)hexane (CXLII), which is moderately active. These authors then disregarded the hypothetical structural resemblance and prepared a series of di(p-hydroxyphenyl)propane derivatives and concluded, on the basis of their results, that this resemblance is coincidental.…”
