Diastereoselective Synthesis of the C(17)−C(28) Fragment (The C−D Spiroketal Unit) of Spongistatin 1 (Altohyrtin A) via a Kinetically Controlled Iodo-Spiroketalization Reaction
摘要:
[GRAPHIC]A convergent and stereocontrolled synthesis of spiroketal 15 corresponding to the C-D fragment of spongistatin 1 has been accomplished by a sequence utilizing a kinetically controlled intramolecular iodo-spiroketalization of glycal 2, which in turn was synthesized via a ring-closing metathesis reaction.
