- A Catalyst Designed for the Enantioselective Construction of Methyl- and Alkyl-Substituted Tertiary Stereocenters
-
Tertiary methyl-substituted stereocenters are present in numerous biologically active natural products. Reported herein is a catalytic enantioselective method for accessing these chiral building blocks using the Mukaiyama-Michael reaction between silyl ketene thioacetals and acrolein. To enable remote enantioface control on the nucleophile, a new iminium catalyst, optimized by three-parameter tuning and by identifying substituent effects on enantioselectivity, was designed. The catalytic process allows rapid access to chiral thioesters, amides, aldehydes, and ketones bearing an α-methyl stereocenter with excellent enantioselectivities, and allowed rapid access to the C4-C13 segment of (-)-bistramide A. DFT calculations rationalized the observed sense and level of enantioselectivity.

- Flexible and modular syntheses of enantiopure 5-cis-substituted prolinamines from l-pyroglutamic acid
-
A wide range (25 examples) of 5-cis-substituted prolinamines is prepared in five to ten steps starting from cheap l-pyroglutamic acid. Three routes, differing mainly in the order of introduction of the substituents at the 5-cis position, the pyrrolidine nitrogen atom, and the exocyclic amino function, are successfully developed.
