Cyclopenta[c]benzofuran derivatives (5a) and (5b) were synthesized from spirodienone esters (6a) and (6b). respectively; and the utility of these intermediates in acorane-alaskane sesquiterpenesynthesis is illustrated by their conversion into(±)-β-acoreno (4a) and (±) and (±)-acorenone (1).
由螺二烯酮酯(6a)和(6b)合成环戊[ c ]苯并呋喃衍生物(5a)和(5b )。分别; 并通过将它们转化为(±)-β-acoreno(4a)和(±)和(±)-acorenone(1)来说明这些中间体在天竺葵-ska草香倍半萜合成中的用途。
