- Studies on the monoalkylation of terminal diynes
-
In our study we intend to find out the favourable conditions for the monoalkylation of terminal diynes by following two reaction pathways. The reaction in DMSO, using dimsyl sodium as metallation reagent and butylbromide for the alkylation, gives up to 80% conversion of terminal diynes to their monoalkyl derivatives. Mass spectra of terminal diynes 1-4 and of the corresponding monobutyl 1a-4a and dibutyl 1b-4b diynes are given.

- EXO- AND ENDOHORMONES. XIV. STEREOSPECIFIC SYNTHESIS OF 3Z, 13Z- AND 3E, 13E-3,13-OCTADECADIEN-1-YL ACETATE
-
The two geometric isomers, 3Z, 13Z-, (I) and 3E, 13E-, (II), of 3,13-octadecadien-1-yl acetate, coponents of the phermonal lure of many lepidopteran insect species, were prepared in high isomeric purity by using 1,11-dodecadiine.
