Effective Synthesis of a Novel Tetrahydrofuran Containing Triterpenoid: 5′(Z)-Benzylidene-tetrahydrofurano[3,2-b]lup-20(29)-en-28-oate

The title compound 5′(Z)-benzylidene-tetrahydrofurano[3,2-b]lup-20(29)-en-28-oate was synthesized with high chemo-, regio-, and stereoselectivity by 5-exo-dig cycloisomerization of methyl 2α-phenylpropynyl-3-oxolup-20(29)-en-28-oate with use of KN(SiMe3)2-DME. The novel betulinic acid derivative was...
