Efficient Syntheses of 1-Arylnaphthalene Lignan Lactones and Related Compounds from Cyanohydrins
摘要:
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.
1-Arylnaphthalenelignans were synthesized in good yields from O-t-butyldimethylsilylcyanohydrins in two steps based on a newapproach involving a tandem conjugate addition-aldol reaction, followed by an acid-catalyzed construction of the naphthalene ring.
