The reaction mechanisms of amino acids with a newclass of fluorogenic reagents were investigated. The structures of colored and fluorescent species formed in these reactions were partially confirmed by experimental evidence. Reaction intermediates, C-N-C 1,3-dipoles derived from imines, were trapped with dipolarophiles in 3 + 2 cycloadditions to form spiropyrrolidines.
An enzymatic decarboxylative aldol reaction was developed for the synthesis of noncanonical α-amino acids containing γ-tertiary alcohol groups. The modularity of the electrophile enabled access to four classes of ncAAs with high efficiency as well as excellent regioselectivity and stereoselectivity.
