A new class of orthoacylimine-derived chiral auxiliaries has been synthesized and tested in the nucleophilic addition of organolithium reagents to imines. The precursors can be prepared by an aza-Wittig reaction between the corresponding orthoacyl azide and a variety of aldehydes

Electron self-exchange has been measured by an NMR technique for horse-heart myoglobin. The rate is 3.1 x 10(3) M-1 s-1 at 23 degrees in 0.1 M phosphate at pH 6.9. The rate was weakly dependent on ionic strength up to

1H-NMR saturation transfer spectroscopy and nuclear Overhauser effect (NOE) have been utilized to assign several heme resonances in the low-spin trimethyl phosphine complex of sperm whale metmyoglobin. The two methods permit the location of the heme methyl resonances and the
