2-Hexyl-5-methyl-1,2-oxaborolane (I) prepared readily by treatment of a mixture of Me vinyl ketone and 1-hexene with borane-dimethyl sulfide, reacted smoothly with LiCHCl2 to give intermediate II which upon oxidation with pyridinium chlorochromate led to 2,5-undecanedione. The latter afforded dihydrojasmone (III) via an intramol. condensation according to known procedure.
