Optically active samples of the N-protected 1,3-cyclobutane amino acids 1 and 2 were prepared from ct-pinene. The synthesis of 1 is enantiodivergent insofar as both optical antipodes of the product can be prepared from the same a-pinene enantiomer. Single crystal X-ray diffraction studies of derivat

Chiral 1,3-Cyclobutane Amino Acids: Syntheses and Extended Conformations. -Oxidative cleavage of verbenone (I) produces the keto acid (II) from which both enantiomers (VIII) and (X) of N-protected 1,3-cyclobutane amino acid can be prepared. An analogous sequence starting from Ξ± -pinene (XI) leads t
