✦ Synopsis

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 α -pinene (XI) leads to the more flexible compound (XIII), an interesting dipeptide surrogate.
