Unexpected 1,3-oxazolidine formation in the attempted oxidation of N- aryl-N-methyl substituted β-amino alcohols using pyridinium dichromate

1,3-Oxazolidines were obtained from the reaction of N-methyl substituted β-amino alcohols with pyridinium dichromate in dichloromethane. A single electron transfer mechanism, SET, is proposed to account for the formation of the 1,3-oxazolidines.
