## Abstract A simple synthesis of a series of bicyclo[m.n.0]β1βalkenes (m, n = 3,4,5) from 2βoxocycloalkanecarboxylates by the intramolecular __Wittig__ reaction is reported (see p. 70β72). The spectral properties (IR., ^1^HβNMR. and ^13^CβNMR.) of these annulated trisubstituted olefins are discuss
