Thietane fused derivatives

Sakamoto et al. also reported the solution photochemistry for la-d, which gave the corresponding thietane-fused -lactams 2a-d as shown in Table 2 [30,31]. For tigloyl derivatives Ic and Id, P-lactams were obtained as a mixture of two stereoisomers (entries 6 and 8). The anti isomers were preferably formed, in ratios of 0.8 and 0.7, respectively. In the solid-state photoreaction of... [Pg.5]

Whereas oxidation leaves the fused thietane derivative 218 intact by giving the corresponding sulfone, reduction produces the 4-isopropyl-l,l-diphenyl-bicyclo[4.1.0]hept-l-ene (219) by extrusion of sulfur (Eq. 58). The general oxidation procedure to convert thietanes to their sulfones comprises refluxing with peracetic acid. [Pg.254]
