The A ring of FR182877, exemplified by ent-4-b,c, has been synthesized, involving an enyne RCM as the key step. A systematic comparison of enyne vs diene RCM for the formation of cyclopentene derivatives showed that the latter metathesis proceeds much more easily even for this ring size.
合成了FR182877的A环,以ent -4-b ,c为例,其中涉及烯键RCM作为关键步骤。对烯炔与二烯RCM形成环戊烯衍生物的系统比较表明,即使在这种环尺寸下,后者的复分解过程也更容易进行。
