LTMP provides higher conversions and diastereoselectivities than LDA in enolate alkylation reactions of these derivatives. For example, treatment of (rac)-10 with 2.5 equiv of LDA followed by alkylation with EtI results in a 70:30 mixture of (rac)-14.

A support-bound tert-butanesulfinamide chiral auxiliary and linker will be useful for the preparation of other classes of compounds. For example, sulfinimines are versatile chiral nitrogen intermediates in asymmetric synthesis (see ref 16 and Davis, F. A.; Portonovo, P. S.; Reddy, R. E.; Reddy, G. V.; Szewczyk, J. M.; Zhou, P. Phosphorus, Silicon Relat. Elem. 1997, 120&121, 291).
