Hepatocellular carcinoma(HCC)is one of the leading causes of cancer-related death in Asian and African countries due to a high prevalence of chronic hepatitis B infections(1,2).The vast majority of current studies focus on the treatment of HCC itself rather than complications from HCC.A potentially life-threatening complication of HCC is spontaneous rupture,and its prevalence has been reportedly to be 5-15%of all HCC cases(1).This is the third leading cause of HCC-related death after tumor progression and liver failure,and there is a high mortality associated with rupture(3,4).

The Reformatsky reagent derived from ethyl bromoacetate circumvents the challenge associated with the direct regio-and enantioselective iridium-catalyzed allylic alkylation with an unstabilized aliphatic ester enolate. Notably, this work represents the first example of using a Reformatsky reagent in a metal-allyl reaction, which permits the direct construction of enantioenriched β-stereogenic homoallylic esters without preactivation of the pronucleophile or post-reaction modification of the product(e.g., thermal decarboxylation of a 1,3-dicarbonyl). Moreover, the process allows the coupling of a broad range of sterically and electronically diverse electrophiles bearing aryl, heteroaryl and alkenyl derivatives, including the significantly more challenging alkyl-substituted allylic carbonates. The versatility of the ester product is exemplified by a series of functional group manipulations and the development of a concise and efficient enantioselective total synthesis of the natural product,(+)-descurainolide A. Finally, mechanistic studies indicate that the zinc enolate behaves as a soft nucleophile that undergoes outer-sphere alkylation.
