چکیده

Dressed to the nines: The first enantioselective total synthesis of (-)-minovincine has been accomplished in nine chemical steps and 13 % overall yield. A novel, one-step Diels-Alder/β-elimination/conjugate addition organocascade sequence allowed rapid access to the central tetracyclic core in an asymmetric manner. Boc=tert-butoxycarbonyl, LG=leaving group, PMB=para-methoxybenzyl.

Nine-step enantioselective total synthesis of (-)-vincorine.

A concise and highly enantioselective total synthesis of the akuammiline alkaloid (-)-vincorine has been accomplished. A key element of the synthesis is a stereoselective organocatalytic Diels-Alder, iminium cyclization cascade sequence, which serves to construct the tetracyclic alkaloid core architecture in one step from simple achiral precursors. The challenging seven-membered azepanyl ring s...

Oxy-Allyl Cation Catalysis: An Enantioselective Electrophilic Activation Mode.

A generic activation mode for asymmetric LUMO-lowering catalysis has been developed using the long-established principles of oxy-allyl cation chemistry. Here, the enantioselective conversion of racemic α-tosyloxy ketones to optically enriched α-indolic carbonyls has been accomplished using a new amino alcohol catalyst in the presence of electron-rich indole nucleophiles. Kinetic studies reveal ...

The enantioselective hydrogenation of olefins, ketones, and imines still represents an important topic in organic synthesis and catalysis. Although many highly enantioselective processes based on chiral Rh, Ru, and Ir complexes have been reported, most of these catalysts failed to give satisfactory results in the asymmetric hydrogenation of aromatic and heteroaromatic compounds. Examples of eff...
