A facile radical cyclization-fragmentation sequence of ω-haloalkyl- tethered spirocyclobutanones, which are readily available by the Kulinkovich cyclopropanation of cycloalkene carboxylates and subsequent electrophilic addition to haloalkyl acetals, provides a convenient method for appending seven- and eight-membered rings onto cycloalkene carboxylates. An enantioselective preparation of a medium-sized carbocycle is possible by the use of a non-racemic, C2-symmetric acetal.
Radical fragmentation of ω-bromoalkyl cyclobutanones. A modular approach to eight-membered carbocycles
Oh, Heong-Sub,Lee, Hyoung Ik,Cha, Jin Kun
, p. 3707 - 3709 (2007/10/03)
(graph presented) An eight-membered ring was conveniently appended onto a cycloalkene carboxylate by employing a facile radical cyclization-fragmentation reaction of an ω-bromoalkyl spirocyclobutanone, which was readily accessible by the Kulinkovich cyclo
