Enantioselective construction of vicinal stereogenic quaternary centers by dialkylation: Practical total syntheses of (+)- and meso-chimonanthine

All three stereoisomers of the hexacyclic 3a,3a'-bispyrrolidino[2,3- b]indoline moiety found in complex indole alkaloids can be prepared, as illustrated by total syntheses of meso-chimonanthine (1) and (+)- chimonanthine (2). A rare example of high diaste

Enantioselective construction of vicinal all-carbon quaternary centers via catalytic double asymmetric decarboxylative allylation

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.

Studies on enol carbonate chemistry: Stereoselective construction of vicinal quaternary benzylic centers in the bis-oxindole series

The Steglich-type intramolecular acyl transfer of bis-oxindole enol carbonate derivatives 9a-c affords selectively the monorearranged products 11a-c. In turn, Pd(0)-mediated allyl transfer of the bis-Alloc derivative 9c allows an efficient double C-allyla
