Tanaka et al.’s Ru(I)-catalyzed [2 + 2 + 2] cyclotrimerization of ethyl cyanoformate (28, 29) also proceeded effectively for diynes 4a,b,d, to afford pyrrolopyridine carboxylates 28a,b,d regioselectively. Deiters and coworkers have carried out similar reactions previously on solid support (27, 30). Similarly, Saito and coworkers’ Ni(0)-catalyzed [3 + 2 + 2] cycloaddition with ethyl cyclopropylidene acetate (31) was translated effectively to solid support-bound diynes 4a–c. The initial cycloheptapyrrolidine ester products were then converted to the correspondingWeinreb amides 29a–c/29′a–c (32) to facilitate downstream separation of E and Z isomers after cleavage from the solid support. |

Tanaka et al.’s Ru(I)-catalyzed [2 + 2 + 2] cyclotrimerization of ethyl cyanoformate (28, 29) also proceeded effectively for diynes 4a,b,d, to afford pyrrolopyridine carboxylates 28a,b,d regioselectively. Tanaka等的氰甲酸乙酯钌催化[2 + 2 + 2]环三聚反应也可高效地以二炔4a、b、d为底物进行并提供区域选择性。Deiters and coworkers have carried out similar reactions previously on solid support (27, 30). Deiters及其同事先前在固相载体上进行了相似的反应。 Similarly, Saito and coworkers’ Ni(0)-catalyzed [3 + 2 + 2] cycloaddition with ethyl cyclopropylidene acetate (31) was translated effectively to solid support-bound diynes 4a–c. 与上述类似，Saito及其同事的ethyl cyclopropylidene acetate 镍催化[3 + 2 + 2] 环化加成也被有效地引入到二炔4a-c为底物的的固相载体合成中。 The initial cycloheptapyrrolidine ester products were then converted to the corresponding Weinreb amides 29a–c/29′a–c (32) to facilitate downstream separation of E and Z isomers after cleavage from the solid support.最初的cycloheptapyrrolidine ester产物随后被转化为相应的Weinreb酰胺29a–c/29′a–c，以利于E和Z同分异构体从载体上解离下来后的下游分离。 |
