Dimethylpropanoic acid, isooctadecyl ester. See Isostearyl neopentanoate N,N-Dimethyl-N-2-propenyl-2-propen-1-aminium chloride, homopolymer. See... [Pg.2090]

Seebach and coworkers have developed the rtmldple coupling reagent, 2-tiitro-2-propenyl 2,2-dimethylpropanoate fNPPi. The reaction of nitromethane v/ith formaldehyde gives 1,3-dihydroxy-2-nitropropane in 95% yield. Subsequent acyladon v/ith two eqidviilents of pivaloyl chloride and elimination of pivalic acid affords NPP. The reacdon may be run on a 40- to 200-g... [Pg.41]
