The reaction of O-tert-butyl-N-(chloromethyl)-N-methyl carbamate (1) with lithium powder and a catalytic amount of DTBB (2.5 mol %) in the presence of different electrophiles [Me3SiCl, Bu(i)CHO, Bu(t)CHO, PhCHO, (CH2)4CO, Et2CO, PhCOMe, Ph2CO] in THF at -78°C leads, after hydrolysis with water, to the expected functionalised carbamates 2. As an example, the hydrolysis of compound 2e with hydrogen chloride affords easy deprotection of the amine functionality yielding the corresponding 1,2-aminoalcohol 3e.
