one step transformation of esters into secondary alcohols (70--80% yields) has been performed with a Grignardreagent in the presence of calcium or zinc borohydride. Under the same conditions, vinylic Grignardreagents gave γ,δ-unsaturated alcohols in good yields through three successive reactions : addition to the ester carbonyl, then conjugate addition and, finally reduction).

survival and redirecting the innate immune response. Recently, we have designed novel and potent macrocyclic pyrrolopyrimidines as MerTK inhibitors using a structure-based approach. The most active macrocycles had an EC50 below 40 nM in a cell-based MerTK phosphor-protein ELISA assay. The X-ray structure of macrocyclic analogue 3 complexed with MerTK was also resolved and demonstrated macrocycles binding
