Abstract—Stable derivatives of oxaphosphaphenanthrenes were prepared using multicomponent reactions of dialkyl acetylenedicarboxylate with 3-bromo-2-naphthol in the presence of trimethyl or triphenyl phosphite in good yields. Chromene derivatives were produced by using triethyl phosphite and dialkyl acetylenedicarboxylate in the presence of OH-acids in excellent yields.
Index Terms—One-pot reactions, acetylenic compounds; chromenes, trimethyl phosphate, Triphenyl phosphite.
