Abstract

The first enantioselective synthesis of (R)-2-cubylglycine, an analogue of (R)-2-phenylglycine in which the phenyl ring has been replaced by cubane, is disclosed. The key step was a telescoped Strecker reaction using (S)-2-amino-2-phenylethanol as a chiral auxiliary. Exploration of an alternative synthetic approach resulted in unprecedented cubane C-H insertion.
