The effect of adding 1 equiv. of an amine or 0.2 equiv. of CuI to a Pd/In bimetallic cascade reaction is described. In the class 1 cascade reaction of aldehydes, aryl iodides and allene, generating homoallylic alcohols, the reaction time is reduced f

Up to four bonds and five stereocentres are created, in five component processes (five point diversity), utilising resin bound aryl iodides by hydroboration or hydrostannylation of alkynes, followed by cyclisation–anion capture involving Suzuki or

Automation in medicinal chemistry is often seen simply as a part of the combinatorial chemistry technologies used to meet the need for large, diverse screening collections for lead generation. However, the application of automation to the lead optimi
