Studies on Reduction-products of Naphtheleneacetate and their Value as Plant Growth Substances

I. Synthe_??_is of 1, 2, 3, 4-tetrahydronaphthalene (1) acetate and 1, 2, 3, 4-tetrahydronaphthalene (2) acetate and their pyhsiolo_??_ical activities

Abstract

To elucidate the relationship between the position of double bonds in hydronaphthalene and its physiological activity I intended to study hydronaphthaleneacetate. First, 1, 2, 3, 4-tetrahyd-ronauhthalene (1) acetate and 1, 2, 3, 4-tetrahydronaphthalene (2) acetate were synthesized from 1, 2, 3, 4-tetrahydronaphthalene by the condensation-method of hydrochloric acid and formalin according to the next formula;
_??_
The position of acetic-radical in these substances was decided by esterification and oxydation of them. According to Raphanus-test, the physiological activity of 1, 2, 3, 4-tetrahydro (1) naphthaleneacetate was generally equal to that of α-naphthaleneacetate.
