  Allylic substitution with sp2-carbon reagents (aryl and alkenyl anions) was realized by using allylic picolinates and copper reagents derived from RMgBr and CuBr·Me2S to afford anti SN2′ products regio- and stereoselectively. Steric and electronic factors in the reagents and the size of the methylene substituents around the allylic moiety marginally affected the selectivity. The reaction system was

• Picolinoxy Group, a New Leaving Group for anti S_N2′ Selective Allylic Substitution with Aryl Anions Based on Grignard Reagents

  The picolinoxy group was found to be an extremely powerful leaving group for allylic substitution with aryl nucleophiles derived from ArMgBr and CuBr*Me2S. The substitution proceeds with anti SN2' pathway and with high chirality transfer. The electron-withdrawing effect of the pyridyl group and chelation to MgBr2 are likely the origin of success. Results suggesting these effects were obtained.

  To establish allylic substitution of secondary allylic alcohol derivatives with alkynyl copper reagents, allylic esters bearing the (2-pyridine)CO2-, (2-pyrazine)CO2-, (EtO)(2)PO2-, C6F5CO2-, o-(Ph2P)-C6H4CO2-, MeOCO2-, or AcO-group were examined. First, picolinate (R-1 = Me, R-2 = CH2OPMB) was subjected to reaction with (TMS-C C)(2)CuLi center dot LiBr at 0 degrees C. Although no substitution took place, MgBr, (3 equiv) was found to promote the reaction to produce the anti S(N)2' product in 93% yield with 94% regioselectivity and 99% chirality transfer. In contrast, substitution of the other esters with the copper reagent in the presence of MgBr, were less reactive ((2-pyrazin)CO2-) or marginally reactive (other cases). Generality of the substitution using picolinates was established with five picolinates (R-1 = Me, Ph(CH2)(2), PMBO(CH2)(3); R-2 = Me, CH2OPMB, CH2OTBS, C5H11, c-C6H11) and seven alkynyl copper reagents (R-3 = TMS, Ph, p-TBSOC6H4, p- and o-MeOC6H4, P-MeC6H4, p-FC6H4), furnishing anti S(N)2' products in 61-93% yields with high regioselectivity (usually > 90%) and high chirality transfer (usually > 95%). In addition, transformation of the products was briefly studied.
