CATALYZED INSERTION REACTIONS OF SUBSTITUTED Α-DIAZOESTERS. A NEW SYNTHESIS OF CIS-ENOATES
Ikota, Nobuo,Takamura, Norio,Young, Stanley D.,Ganem, Bruce
, p. 4163 - 4166 (2007/10/02)
The decomposition of α-diazoesters is notably catalyst-dependent; with rhodium (II) carboxylates a stereoselective insertion reaction leads to the title structures in high yield.
