Abstract
Summary: Oxetanes are cleaved at 0" C in tetrahydrofuran by lithium 4, 4'-di-tert- butylbiphenylide, giving lithium y-lithioalkoxides which can provide 2-substituted tetrahydrofurans by trapping with aldehydes and ketones followed by acid cyclization of the resulting 1, Qdiols; the cuprates of these dianions undergo conjugate addition and nucleophilic substitution reactions.
