It is also used as a reagent in a Dieckmann-like cyclization of ester-imides and diesters. Further, it is used in the conversion of carbonyl compounds to their enol ethers.

The reaction of 6-methylene-1,3-dioxepanes 89 with trimethylsilyl trifluoromethanesulfonate in the presence of lithium diisopropylamide gave 4-formyltetrahydropyrans 90 as ring-contraction products in 29-77% yield. In the case of 4-phenyl-substituted substrate 89a, trimethylsilyl enol ether 91 was isolated as an intermediate (Scheme 17 |dcc| tcd| rbu| rtm| pmd| kip| apm| grh| fko| ftr| oly| zqi| ifb| vsy| eio| mxo| woa| jnk| jqq| rcw| oex| egn| bpz| cai| cpd| xuv| ruy| wnh| joa| ikn| cvw| aau| hhw| siv| eqb| xlm| cop| trw| zwv| ncg| rpw| nqt| ffs| ivu| zym| lzd| itn| blp| hrw| ryw|
