Synthesis and Liquid Crystal Properties of Dimethylene Linked Compounds Incorporating the Cyclobutane or Spiroheptane Rings

The preparation of sixteen dimethylene linked compounds is described heptane ring>, and a comparison is made between the transition temperatures of these compounds and those of the corresponding esters.This comparison once again highlights the fact that the cyclobutane ring should be regarded, in terms of its ability to promote nematic thermal stability, as a "chain stiffener rather than as a ring system.A comparison is also made of the nematic thermal stabilities of the trans-cyclobutane and the spiroheptane systems and of the trans-cyclohexane and the spiroundecane systems.

STUDY OF THE ANOMERIC EFFECT IN 2-SUBSTITUTED 1,3-DITHIANES

The conformational analysis of several 2-substituted 1,3-dithianes made possible the evaluation of S-C-Y anomeric interactions, where Y=SCH3,SC6H5,CO2CH3,COC6H5,CO2H and N(CH3)2.The relative magnitude of the effects observed for these groups odithiane(Y)-ΔGocyclohexane(Y)> can be explained in terms of the combined influence of dipole/dipole and two-electron stabilizing interactions (stereoelectronic effect).

LONG-ACTING CONTRACEPTIVE AGENTS: CYCLOPROPYL AND CYCLOBUTYL ESTERS OF NORETHISTERONE

Several esters of norethisterone (17α-ethynyl-17β-hydroxyestr-4-en-3-one) with carboxylic acids containing a cyclopropyl or cyclobutyl ring have been synthesized and the stereochemistries of the side-chains determined.
