Enantioselective organocatalysis using SOMO activation

WebUsing SOMO Activation Teresa D. Beeson, 1,2Anthony Mastracchio, Jun-Bae Hong,1,2 Kate Ashton, 1,2David W. C. MacMillan * The asymmetric a-addition of relatively nonpolar … WebAbstract. The asymmetric α-addition of relatively nonpolar hydrocarbon substrates, such as allyl and aryl groups, to aldehydes and ketones remains a largely unsolved problem in … The reaction in Fig. 1b was also instrumental to the discovery that the synthetic potential of chiral enamines is not limited to the ground-state domain, and can be expanded by exploiting their photochemical activity. During investigations into the direct α-alkylation of aldehydes with electron-deficient alkyl … See more The discovery that the catalytic functions of enamines could be expanded by exploiting their excited-state reactivity61 motivated the quest for other chiral … See more The photochemical organocatalytic strategies discussed so far all relied on the stereoselective interception of photogenerated radicals or radical ions in … See more Recently, a strategy has been reported that exploits the excited-state reactivity of common biological cofactors to enable enzymes to catalyse completely different … See more define notational analysis
