| Abstract: | An improved synthesis of nereistoxin, 4-dimethylamino-1, 2-dithiolane (Ia), has been achieved in a 3-step sequence starting from 1, 3-bis (benzylthio)-2-propanone (IIa) or 2-phenyl-1, 3-dithian-5-one (IVa). By the similar route 4-amino-1, 2-dithiolane (Ib), 4-methylamino-1, 2-dithiolane (Ic) and two S-acyl derivatives (VIa, b) of dihydronereistoxin were synthesized and their insecticidal activities were tested. |
