2-Selenenyl and 2-sulfenyl methyl 4-oxoalkanoates 5 and 7 are obtained in good yields by reaction of methyl 2-siloxycyclopropanecarboxylates 1 with phenylselenenyl chloride or a sulfenyl chloride in the presence of catalytic amounts of titanium tetrachlor
Lewis Acid promoted Additions of Cyclopropanes to Iminium Salts: A New Possibility for α-Methylene-γ-Butyrolactone Synthesis
Reissig, Hans-Ulrich,Lorey, Hiltrud
, p. 269 - 271 (2007/10/02)
Methyl 2-siloxycyclopropanecarboxylates (1) smoothly add to dimethylmethyleneammonium trifluoromethanesulphonate, generated in situ, or to the corresponding iminium chloride (4) in the presence of TiCl4, giving α-aminomethylated γ-oxoesters (6) in good yi
