  The introduction of P4 substituted 1-methylcyclohexyl groups into Boceprevir®: A change in direction in the search for a second generation HCV NS3 protease inhibitor

  摘要：

  In the search for a second generation HCV protease inhibitor, molecular modeling studies of the X-ray crystal structure of Boceprevir (R) 1 bound to the NS3 protein suggest that expansion into the S4 pocket could provide additional hydrophobic Van der Waals interactions. Effective replacement of the P4 tertbutyl with a cyclohexylmethyl ligand led to inhibitor 2 with improved enzyme and replicon activities. Subsequent modeling and SAR studies led to the pyridine 38 and sulfone analogues 52 and 53 with vastly improved PK parameters in monkeys, forming a new foundation for further exploration.

  The reaction of silylketene acetals with acryloyl, methacryloyl and crotonyl chlorides gave, after addition of methanol, mainly substituted glutaric esters, probably via a (2 + 2) cycloaddition.

  A mild and efficient transprotection of alcohols from silyl ethers 1a-f to benzoates 2a-f is reported in fair to good yields (50-98%). This silyl-acyl exchange reaction proceeds readily in ­acetonitrile at room temperature in the presence of benzoyl fluoride and DMAP as an acyl transfer catalyst. A two-step ‘one-pot’ DMAP-catalyzed silylcyanation-transprotection sequence which gives the corresponding O-benzoyl cyanohydrines 2g-l in high yields (72-98%) from various benzaldehyde and ketone derivatives is also reported. This original organocatalytic acyl transfer process was also found to be effective in the O-benzoylation of trimethysilyl enolates 1m-o, providing enol esters 2m-o. Lastly, the potential of this strategy is also illustrated by a DMAP-mediated Claisen condensation between ketene silyl acetals 1p-r and benzoyl fluoride.

  本文报道了一种温和且高效的硅醚保护的醇（1a-f）向苯甲酸酯（2a-f）的转化反应，产率良好至优秀（50-98%）。该硅基-酰基交换反应在室温下，以乙腈为溶剂，在苯甲酰氟和DMAP作为酰基转移催化剂的存在下易于进行。同时，还报道了一种两步“一步法”DMAP催化硅氰化-转移保护序列，从各种苯甲醛和酮衍生物得到相应的O-苯甲酰氰醇（2g-l），产率高达72-98%。这种原创的有机催化酰基转移过程在O-苯甲酰化三甲基硅烯醇盐（1m-o）中同样有效，生成烯醇酯（2m-o）。最后，通过DMAP介导的烯酮硅缩醛（1p-r）与苯甲酰氟的Claisen缩合反应，也展示了该策略的应用潜力。
