Nitrochlorination of methyl tricyclo[4.1.0.02,7]heptane-1-carboxylate and phenyl tricyclo[4.1.0.02,7]hept-1-yl sulfone
摘要:
Treatment of methyl tricyclo[4.1.0.0(2,7)]heptane-1-carboxylate and phenyl tricyclo[4.1.0.0(2,7)]hept-1-yl sulfone with a similar to 1:8 mixture of N2O4 and NOCl in diethyl ether at -5 to 0 degrees C gave products of formal anti-addition of NO2Cl at the central C-1-C-7 bond. In the reaction with phenyl tricyclo[4.1.0.0(2,7)]hept-1-yl sulfone nitryl chloride acts as an effective chlorinating agent; as a result, a mixture of diastereoisomeric syn- and anti-6,7-dichlorobicyclo[3.1.1]hept-6-yl phenyl sulfones at a ratio of 7.5: 1 is formed.

Successive treatment of 1-phenylsulfonyltricyclo[4.1.0.0(2,7)] heptane with butyllithium and ethyl nitrate leads to the formation of 7-nitro-7'-phenylsulfonyl-1, 1'-bi(tricyclo[4.1.0.0(2,7)] heptane) through intermediate tricyclo[4.1.0.0(2,7)]hept-1 (7)-ene which is generated by 1,2-elimination of benzenesulfinic acid from the initial compound. Analogous treatment of 1-phenyltricyclo[4.1.0.0(2,7)]heptane gives 1-nitro-7-phenyltricyclo-[4.1.0.0(2,7)]heptane.
