We report on the synthesis of bicyclic 1,3-dienylborates (1a/1b and 2a/2b), wherein the boron and nitrogen atoms are chiral. The absolute configuration of these molecules was established by single X-Ray diffraction studies and qualitative homonuclear NOE difference spectroscopy. The conformational stability of these molecules is low at ambient or subambient temperature. The diastereomeric borates (2a/2b) were found to be very reactive toward dienophiles in the Diels-Alder reaction.
