Reaktionsschritte
Aldehyde 11 was synthesized by radical addition (Lub et al. (1997) Liebigs Ann. Recueil, 2281-2288) of thioacetic acid to 4-vinylbenzaldehyde. Vinyl benzaldehyde was synthesized by the procedure of Ren et al. (1993) Bull. Chem. Soc. Jpn. 66: 1897-1902 with the following changes: The addition of DMF was performed at a 38 mmol scale at 0° C. Purification by column chromatography (silica, Et2O/hexanes, 1:3) afforded 4-vinylbenzaldehyde in 60% yield (FIG. 37)/
