The 13C nmr spectra of 14 β-cyclopropylidenic alcohols 1 have been determined: .All the chemical shifts were assigned and the substituent effect are discussed as a function of molecular conformation.The stereochemistry of two diastereoisomers of alcohols 1e ( R1 = R2 = H; R2 = R4 = CH3 ) and 1k ( R3 = H; R1 = R2 = R4 = CH3 ) was established from ir spectroscopy and 1H nmr results.The 13C nmr spectra of products arising from hydrolysis of 3-cyclopropylidene propanol 1a and 4-cyclopropylidene 2-butanol 1b tosylates have been also recorded.The analysis of these date enables us to establish unambigiously the structure and the stereochemistry of the hydrolysis products.
