Tetrahedron Lett.1983, 34, 3559. volumoso ligado ao átomo de nitrogênio, o qual se encontra em anti em relação ao anel aromático.Buscando-se outro substrato que poderia ser reduzido ao amino derivado correspondente, 28 conforme método mencionado para síntese de 1-amino-2-tetralonóis (página 56, ver parte de objetivos), iniciamos a preparação da O-metil-oxima da 2metilsulfinil-1-tetralona(52). Este composto foi obtido pela sequência de reações mostrada no Esquema 23, em 64 % de rendimento global.…”
