Abstract
1,8-Dibromonaphthalene (II) is aminated to give 1-amino-8-bromonaphthalene (III) which undergoes cyclization reaction with potassium phthalimide (I) to produce phthaloperin-12-one (IV).
ChemInform Abstract
1,8-Dibromonaphthalene (II) is aminated to give 1-amino-8-bromonaphthalene (III) which undergoes cyclization reaction with potassium phthalimide (I) to produce phthaloperin-12-one (IV). 8-Iodo-1-isothiocyanatonaphthalene prepared from (V) is reduced and then cyclized, forming the naphtho-1,3-thiazine (VI).
