An efficient synthesis of 1‐(benzothiazolylamino)methyl‐2‐naphthols has been developed in water by one‐pot condensation of 2‐naphthol, aldehydes and 2‐aminobenzothiazole catalyzed by sodium dodecyl sulfate. Advantages of the methodology include a very short reaction time, excellent yields and catalytic use of the sodium dodecyl sulfate.

New chiral 1-(arylamino)imidazo[2,1-a]isoindole-2,5-dione derivatives were obtained in good to excellent yields via the cyclocondensation of 2-formylbenzoic acid and various α-amino acid arylhydrazides using water as the solvent in the presence of sodium dodecyl sulfate as the surfactant and under simple and minimum manipulation, without purification. The reaction is totally diastereoselective and gives access to the nitrogenated tricyclic core with a relative trans stereochemistry.
