Gv. Gavrilova et al., SYNTHESIS AND STRUCTURE OF LORO-6-METHYLTRICYCLO[4.1.0.0(2,7)]HEPT-4-EN-3-ONE, Russian chemical bulletin, 46(9), 1997, pp. 1565-1568
The reaction of -4-dichloromethyl-4-methylcyclohexa-2,5-dien-1-one wit
h (Me3Si)(2)NNa yielded loro-6-methyltricyclo[4.1.0.0(2,7)]hept-4-en-3
-one (substituted tropovalene). The structure of the title compound wa
s established by H-1 and C-13 NMR spectroscopy and X-ray diffraction a
nalysis.
