                                    1-Arylnaphthalene lignan lactones were synthesized in good yields from O-(tert-butyldimethylsilyl)cyanohydrins in two steps based on a conjugate addition-aldol reaction, followed by acid-catalyzed closure to form the naphthalene ring. 4-Hydroxy-1-arylnaphthalene lignan lactones were also synthesized by conjugate addition-aldol reaction, followed by aromatization-lactonization.
