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
WebThe MCRox1 hyperfine parameters are best interpreted in terms of a Ni dx2-y2 SOMO, although a pure dx2-y2 SOMO does not explain the fact that about 7 % of the spin-density resides on the sulfur.
