acrylate; in this case, we have isolated the β diketone corresponding to the 1,2 addition product. With 2-methyl cyclohexanone, the addition takes place only on the less hindered carbon. With aldehydes, the Michael reaction is not possible because of the predominating aldolisation. With unreactive donors such as tert-butyl methyl ketone and disobutyl ketone, reactive acceptors as ethyl crotonate or cyclohexenone

(e.g., ZCZ011) featured a 3-nitroalkyl-2-phenyl-indole structure. Although a small number of drugs include the nitrogroup, it is generally not regarded as being "drug-like", and this is particularly true for aliphaticnitrogroups. There are very few case studies where an appropriate bioisostere replaced a nitrogroup that had a direct role in binding. This may be indicative of the difficulty of replicating

reported: Si-H activated by KF or CsF is a very powerful and selective reducing reagent; the carbonylgroup of aldehydes, ketones or esters can be reduced without reduction of other functional groups (C&z.dbnd;C, NO2, Br, amido). Furthermore, selective reductions of aldehydes in the presence of ketones and ketones in the presence of carboxylic esters are also possible. CsF in the presence of Si(OR)4 is

cyano C1 unit and ethynyl C2 unit are regiospecifically introduced to the γ‐position of ketones at room temperature, providing a mild yet powerful method for production of elusive aliphatic nitriles and alkynes. All transformations described are based on a common sequence: 1) oxidative ring‐opening of cyclobutanol substrates by C−C bond cleavage; 2) radical addition to triple bonds bearing an arylsulfonyl
