Abstract
Convenient and practical synthesis of N-Boc- and N-Cbz-α-amino stannanes from the corresponding α-amido sulfones was achieved. Yields of products are generally good to high because of the consequence of avoiding the isolation of unstable imine intermediates. The procedure is so simple that large-scale stannylation is possible without any difficulty.
Key words
stannylation - imines - sulfones - tin - fluoride
