We have synthesized two new series of chiral esters, the (R)-4'-(2-chloropropoxy)phenyl 4-alkoxybenzoates (3) and the (R)-4'-(2-chloropropoxy)phenyl 4-alkoxycinnamates (4).Compounds belonging to the former series mainly exhibit smectic A phases at moderate temperatures (about 50 deg C) while the compounds of the latter series show A phases at somewhat higher temperatures.Some members of both series show, in addition, a cholesteric or a smectic B phase but tilted are not found at all.Keywords: chiral smectics, phenyl benzoates, phenyl cinnamates.
