We report a catalytic stereoconvergent construction of vicinal all-carbon quaternary centers via double stereoablative enantioselective alkylation of a mixture having racemic and meso diastereomers of esters to afford exceptional levels of diastereo- (up to 17:1) and enantioselectivity (up to >99% ee). The strategy offers an efficient and general approach to dimeric cyclotryptamine alkaloids sharing a labile C3a-C3a′ σ-bond in the hexahydropyrroloindoline core.

Paragraph 0032-0039, (2017/08/19)
The invention relates to an isoindigo derivative and a preparation method thereof. A structural formula of the isoindigo derivative is described in the specification, wherein R1 is H, 4-OCH3R2=Bn, n-Bu, i-Pr, 2-Bu, (4-OCH3)-Bn and n-C12H25. The preparation method of the isoindigo derivative comprises the following steps: A, mixing an o-bromoacetanilide compound, copper acetate monohydrate, iodosobenzene diacetate, potassium hydroxide and dimethyl sulfoxide, heating and carrying out reaction; and B, after reaction is finished, purifying, so that the target product isoindigo derivative is obtained. The preparation method of the isoindigo derivative has the advantages that single raw material is adopted, specificity is good, and yield is high.
