The t-Bu-P4 base was found to be an excellent catalyst for activatingorganozincreagents and was used to promote the S(N)2' reaction of alpha,beta-unsaturated esters bearing a gamma-chloride using various organozincreagents: these reactions proceeded in high yields with excellent chemo-and regioselectivity.
The tBu‐P4 base was found to be an excellent catalyst for the activation of organozincreagents. The base was used to promote the SN2′ reaction of α,β‐unsaturated esters bearing a γ‐chloride in the reactions with various organozincreagents in the presence of LiCl. The reactions proceeded in high yield with excellent chemo‐and regioselectivity. The role of LiCl appears to be the activation of the γ‐chloride
所述吨卜-P4基被认为是对有机锌试剂的激活的良好催化剂。该碱用于在LiCl存在下与各种有机锌试剂反应中促进带有γ氯化物的α,β-不饱和酯的S N 2'反应。反应以高收率进行,具有出色的化学和区域选择性。LiCl的作用似乎是α,β-不饱和酯的γ-氯化物的活化,这已通过NMR光谱学研究证实。

Optimization of macrocyclic inhibitors of FXIa is described which focused on modifications to both the macrocyclic linker and the P1 group. Increases in potency were discovered through interactions with a key hydrophobic region near the S1 prime pocket by substitution of the macrocyclic linker with small alkyl groups. Both the position of substitution and the absolute stereochemistry of the alkyl groups
