Metal-Free Regiodivergent Addition of Carbon Nucleophiles to ?,?-Unsaturated Electrophiles.


ABSTRACT: A mild and metal-free regiodivergent addition of carbon nucleophiles to ?,?-unsaturated electrophiles was developed. Total 1,2-regioselectivity was observed in the addition of nitrobenzyl chloride derivative 1 to ?,?-unsaturated aldehydes 2 in the presence of TDAE. Moreover, the reaction between p-nitrobenzyl chloride 1a and ?,?-unsaturated iminium salts 4 led to the formation of the 1,4-adduct with total regioselectivity.
