C-C-Bond Formation by Lewis Acid Induced Cyclopropane Ring Cleavage - New Routes to Highly Substituted Furan(one) Derivatives
Reissig, Hans-Ulrich,Reichelt, Ingrid,Lorey, Hiltrud
, p. 1924 - 1939 (2007/10/02)
Activation by stoichiometric quantities of titanium tetrachloride allows addition of ketones to methyl 2-siloxycyclopropanecarboxylates 1, which affords hydroxylalkylation products 3/4 under ring cleavage.There are, however, restrictions regarding the cyc
LEWIS-ACID-PROMOTED ADDITIONS OF CARBONYL COMPOUNDS TO DONOR-ACCEPTOR SUBSTITUTED CYCLOPROPANES: A NEW SYNTHESIS OF 2,3-DIHYDROFURANE DERIVATIVES
Reissig, Hans-Ulrich
, p. 2981 - 2984 (2007/10/02)
Methyl 2,3-dihydrofurane-3-carboxylates are synthesized from siloxycyclopropaneesters and ketones in the presence of TiCl4 with good yields.
