Abstract

The reduction of nitronate adducts from 1-methoxy-4-nitronaphthalene and Grignard reagents (CH3 MgX, PhCH2CH2HgX, i-C3H7 MgX, c-C6H11MgX and t-C4H9MgX) with hexamethyl phosphorous triamide and phosphorous trichlorlde is reported. With the former reagent the reaction is chemio and stereoselective and only the E-oxime is recovered being the E-2-alkyl-4-methoxy-1 (2H) naphthalenone oximes and the E-2-alkyl-2, 3-dihydro-1, 4- ...
