First synthesis of the difuransesquiterpene athanasin and the elucidation of its relative and absolute configuration
摘要:
The synthesis of the naturally occurring difuransesquiterpene athanasin is described. Employing Seebach's method of ''self-reproduction of chirality'', the chiral oxirane 6 is built up, which is successively connected with suitable furan building blocks. Cyclization of the resulting diols 14 a/b gives the enantiomerically pure diastereomers 1a and 1b.Comparison of their spectroscopic data with athanasin after separation allows the elucidation of the natural product's relative and absolute configuration.
