Environmentally benign, sequential synthesis of 3,4-dihydro-2H-1,4-benzoxazines under phase transfer catalysis conditions / D. Albanese, A. Donghi, D. Landini, V. Lupi, M. Penso. - In: GREEN CHEMISTRY. - ISSN 1463-9262. - 5:4(2003), pp. 367-369.
Abstract:
An environmentally friendly synthesis of 2-substituted 3,4-dihydro-2H-1,4-benzoxazines has been carried out in a sequential fashion through the R4N+F- catalyzed ring opening of epoxides with arylsulfonamides, followed by in situ cyclization of the hydroxysulfonamides thus obtained with NaOH aq. and n-C14H29N+Me3Cl-.
