The sulfuric acid-promoted reaction of benzo-15-crown-5 O) and benzo-18-crown-6 (6) with aliphatic aldehydes, leading to the formation of anthracene crown et~rs, was studied. A substantial substiment effect on the reaction comse was found. For the isdmtyi group the highest yield was obtained, while

## Abstract Regiospecific syntheses of tritium labelled precocene I (**5a**) and precocene II (**5b**), the antijuvenile hormones, have been accomplished. The syntheses involved condensations between 2‐hydroxyacetophenones (**1**) with acetone‐T to give cross condensation products **2** which on cy

Che synthesis and chemistry of macrocyclic polyethers are currently receiving a great deal of attention. Very recently Cram and co-workers 132 have reported the synthesis of two crown ethers (3,~ and QJ). We have prepared two series of novel crown ethers in which respectively, the 1,3and 2,5-positio
