id verčiau naudoti natrio jo pigiau ir D ar L viskas priklauso nuo cheminės sumažintas ir mechanizmas, tai užtrunka šiek tiek problemų sprendimo mūsų mokytojas naudojo davė naudoti šiuos klausimus, bet keletas kur galėtų atsakyti, aint lengva ir kartais negali būti pasakyta id ne eksperimentais

It's true, the birch reduction isn't just for drugs, it is used an many synths, but you'd be remiss to use Na because the product of the birch reaction is 11% with sodium and 75% with lithium . Lithium is free from old batteries and sodium metal is expensive. The birch has 2 simultaneous reactions going on . If you use ephedrine/pseudoephedrine or any chiral precursor, you will get 95%+ the isomer with the chirality of the precursors. If your precursor is racemic, your product isnracemic
