Ten lignans (2-11) and a series of azalignans including 1-aryl-pyrronaphthalenes 20-24 and 3-N-alkylaminomethyl-1-arylnaphthalenes 25-28, structurally related to two HIV reverse transcriptase inhibitors, retrojusticidin B and phyllamyricin A, were prepare

Treatment of phyllanthin (1) with TTFA in TFA gives dibenzocyclooctadiene (2) and phyltetralin (3). Treatment of (1) with DDQ in TFA also affords (2) while with DDQ in acetic acid gives 1-phenylnaphthalenic lignan (4). Synthesis of halophyllanthins (5,6,7) and its Ullmann reaction in ultrasonic condition affords reductive dehalogenated product (1) instead of (2). Treatment of (1) with POCl3 in TCA gives (+) 3,4-diveratryltetrahydrofuran (8) and its conversion to (9) also reported. Treatment of (5) with TTFA/TFA gives (9).
