Free radical initiated ringexpansion of twelve-, thirtheen-, and fourteen-membered carbocyclicrings is described together with a new synthesis of (R)-(−)-muscone.
Free radical-promoted, one-carbon, ring expansion of twelve, fourteen-, and fifteen-membered cyclic β-keto esters is described. The method is then extended to include a three-carbon ring expansion of cyclododecanone, the targets being (±)-muscone and naturally occurring (R)-(−)muscone.
