arylmethanols bearing 1,2,3‐triazoles are achieved using a sequential approach based on the enantioselective alkynylation of aldehydes followed by a one‐pot two‐step desilylation/CuAAC, providing the corresponding products with excellent yields and high enantioselectivity. The application of the reaction has been demonstrated in the synthesis of a 1,2,3‐triazole analog of antihistaminic and anticholinergic
