NORFLURAZEPAM OPTIONS

proceeded by nucleophilic substitution with phenol 119 to generate intermediate B by means of an interrupted PummererPummerer reaction. Many derivatives of benzofuran heterocycles 121 have already been ready by this novel methodology contemplatingThe Pd-catalyzed intramolecular Heck reaction in the construction of the benzofuran ring is a well-know

The synthesis of two-aryl/alkyl benzofurans by intramolecular photochemical Wittig reaction is realized by photochemical reaction. You can find much less more by-products and solutions while in the response and will be managed while the reaction also meets the inexperienced chemical specifications, even so the compound generate is fairly reduced In
