Article abstract of DOI:10.1016/S0040-4039(97)10579-2

The Lewis acid mediated desymmetric intramolecular cyclization of prochiral allylstannyl diketone 1 gave a mixture of two diastereomers 2 and 3. Highly diastereoselective synthesis of each diastereoisomer was accomplished by proper choice of the Lewis acids.
