Stereospecific synthesis of N-acyl-(E)-vinyl-, dienyl-, and enynylsulfoximines
Paley,Snow
, p. 5853 - 5856 (2007/10/02)
A β-tosylvinylsulfoximine, 5, was used as the common starting point for the preparation of the title compounds. Treatment of 5 with 'higher-order cuprates' or trialkylalanes (with a Pd(II) catalyst) afforded N-TBDMS-(E)-vinylsulfoximines, whereas dienylsu
