I've always thought that benzaldehyde + nitroalkane -base-> nitroalkene, but I just read about making ephedrine via a nitroalcohol, formed, from what I can tell, by the exact same reaction. Whats the deal?

PhCHO + CH3-CH2-NO2 -----> PhCHOH-CH(NO2)-CH3 --(-H2O)--> PhCH=CH(NO2)-CH3

Check any organic chemistry textbook.
