Tosylamide cascades

Scheme 6. Reaction scheme for the synthesis of tosylamide cascades. Scheme 6. Reaction scheme for the synthesis of tosylamide cascades.
An asymmetric cascade allylic amination/cycloaddition of furan-2-ylmethanamine tosylamide with O-Boc methyl 2-(hydroxy(phenyl) methyl) acrylate provided a protocol to construct enantioenriched azapolyheterocycles (130BC7080). [Pg.196]

Examples of two C-C bond formation have also been reported. Thus, the addition of sulfone (12) to A-allyl, A-prenyl tosylamide affords the adduct (13) in 68% yield as a mixture of stereoisomers (equation (73)) [141]. The reaction mechanism has the following radical cascade sulfonyl radical addition to diene, 5-exo cyclization, intermolecular C-C bond formation by addition to allyl sulfone and ejection of sulfonyl radical. [Pg.344]
