## Abstract The mass spectra of the title compounds differ considerably depending on the annulation of the bicyclic skeleton. For a series of alkyl derivatives the __cis__‐annulated compounds show a higher abundance of the products due to the retro Diels‐Alder cleavage than the corresponding __tran

This paper reports on the assignment of the 1H and 13C NMR spectra of 14 bicyclo[4.2.0]octane derivatives. Resonance assignments were made on the basis of one-and two-dimensional NMR techniques which included 1H, 13C, DEPT, HMQC and 1HÈ1H COSY and also 1D NOE di †erence spectroscopy. The ratio of th
The 1H and 13C NMR resonances of ten bicyclo[4.3.0]and bicyclo[6.3.0]-c-lactones and a-carbomethoxy-c-lactones were completely and unambiguously assigned by a combination of homonuclear (gs-COSY), 1H-detected heteronuclear one-bond (gs-HMQC) and long-range (gs-HMBC) gradient-selected correlation exp
