Reduction of cis-bicyclo[6,1,0]nona-2,4,6-triene in ammonia and in hexamethylphosphoramide–tetrahydrofuran
Abstract
Alkali-metal reduction, followed by protonation, of cis-bicyclo[6,1,0]nona-2,4,6-triene in polar media gives convenient yields of cis,cis,cis-cyclonona-1,3,6-triene in a highly selective manner as indicated by labelling experiments.
