Australian rainforest, was synthesised from (+)-2-carene in seven steps. This endeavour not only established the absolute stereochemical assignment as (8R,9S)-EBC-329, but also identified, via photoisomerisation, a new seco-casbane family member.
第一开环在七个步骤
2-蒈烯- -casbane,EBC-329,从澳大利亚雨林中分离,由(+)合成。这一努力不仅建立的绝对立体
化学的赋值,因为(8 - [R 9小号)-EBC-329,而且还确定,通过光异构化,新的开环-casbane家族成员。
