Ref. 8 should read: 8 (a) Jahn and co-workers have elegantly demonstrated this strategy in the cyclisation of a number of malonates onto allylsilanes in the presence of LDA and ferrocenium hexafluorophosphate. For example, the malonate 12 [R1⁄4Et, R01⁄4Me; (E)/(Z), 1:10] gave the vinyl cyclopentene 16 (R1⁄4Et) in 98% yield see |
