, p. 269 - 271 (1986)
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
Selenenylation, Sulfenylation, and Aminomethylation of Methyl 2-Siloxycyclopropanecarboxylates by Lewis Acid Induced Ring Cleavage
Reissig, Hans-Ulrich,Lorey, Hiltrud
, p. 1914 - 1923 (2007/10/02)
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
