isocyanate; ClSO2NCO) led to the tricyclic lactams 6 and 8 corresponding to the initial formation both of the tertiary carbenium and α-cyclopropylcarbenium ions (Scheme 2). A number of opticallyactivederivatives of β-amino acids which are promising compounds for further use in asymmetric synthesis were synthesized from the lactams (see 16, 17, and 19–21 in Scheme 3).

New chiral Schiff bases were synthesized through tricyclic 2-azetidinones as key intermediate products which were obtained by reaction of (+)-2-carene with chlorosulfonylisocyanate.
