We have developed a Br?nsted acid catalysed highlyortho-selective functionalization of free phenols with readily availableN,O-acetals under mild conditions, furnishing various corresponding aminomethylated phenol products in moderate to excellent yields. The salient features of this transformation include mild conditions, good substrate scope, excellentortho-selectivity, high efficiency, and ease of further transformation.

(equation presented) A new and general four-step synthesis of protected a-substituted and α,α-disubstituted amino acids has been developed. The key step involves intramolecular ammonium ylide generation from a copper carbenoid with concomitant [2,3] rearr
