A SYNTHETIC APPROACH TO TAXANE DITERPENES. A SYNTHESIS OF THE BICYCLOUNDECENONE RING SYSTEM
Ohtsuka, Yasuo,Oishi, Takeshi
, p. 203 - 206 (1986)
Bicycloundecenone 2 corresponding to A and B rings in taxane diterpenes was synthesized.The eight-membered ring was constructed by a base-induced intramolecular cyclization of twelwe-membered lactam sulfoxides 15.
