Regioselective Reductive Ring Cleavage of 3-Benzyltetrahydro-1,3-oxazines to 3-Dialkylaminopropanols and of 3-Benzyl-3-methyltetrahydro-1,3-oxazinium Iodides to Alkyl 3-Dialkylaminopropyl Ethers

3-Benzyltetrahydro-1,3-oxazines and their methiodides are ring-cleaved upon reduction with lithium aluminum hydride to give 3-dialkylaminopropanols or alkyl 3-dialkylaminopropyl ethers, respectively, in good yields.The reducing agent regioselectively clea
