A ring closing alkyne metathesis reaction catalyzed by the
molybdenum complex 26 followed by a Lindlar reduction of the resulting
cycloalkyne product opens an efficient and stereoselective entry into
epothilone A and C.
在钼络合物 26 的催化下进行闭环炔烃偏析反应,然后对生成的环烷烃产物进行林德拉还原,从而高效、立体选择性地进入表噻吩酮 A 和 C。

as 15, 16 and 20 which themselves were shown to be catalytically active. Numerous applications illustrate the performance of the catalytic system 1/CH2Cl2 which operates under mild conditions and tolerates an array of polar functional groups. The wide scope allows the method to be implemented into the totalsynthesis of sensitive and polyfunctional natural products. Most notable among them is a concise
