Microwaves in Organic Synthesis, 2 Volume Set
The methyl stereocenter was installed using Evans's oxazolidinone methodology, and the trisubstituted chloroolefin was obtained by silyl stannylation of a triple bond. The synthetic route started with palladium-mediated silylstannylation of the ...

The reaction at 25 °C gave no chloroolefin 6 but three optically active products, 4, 5 and 7 ([2]; +4- +7"). The chlorination afforded different product species from those obtained in the bromination. The formation of 7 as a typical different product ...

Asymmetric Synthesis - Tom 3 - Strona 378
In both the chloroolefin and acetylene series (Scheme 16), cyclization of the monocyclic derivatives leads to a predominance of the more stable cis hydrindane under most conditions (114). In contrast, in the bicyclic series with the unsaturated ...

The Chemistry of Rotational Isomers
The difference with respect to the bromine addition is caused by the higher affinity of the chloride ion toward the proton. The chloroolefin (48) originally obtained was a mixture of ca. 10:1 trans and cis isomers. In these halogen additions to the ...

Our approach to kifunensine consists of precise and stereocontrolled peripheral functionalization of the cis-diol 1c and oxidative cleavage of the chloroolefin in 22 to a carboxylate. This reaction involves reductive workup, so that the aldehyde ...
