Synthesis and some reactions of 3,3,6-trisubstituted tricyclo[3.2.0.01,4]heptan-2-ones
Abstract
Electrophiles and most nucleophiles react with tricyclo[3.2.0.01,4]heptan-2-ones with preferential cleavage of the C(1)–C(4) or C(1)-C(5) bond; X-ray data show the highly strained tricycloheptanone (14) has a bond angle of 149.2(9)° at a tetravalent carbon atom.
