Rapid continuous photoflow synthesis of naturally occurring arylnaphthalene lignans and their analogs

Naturally occurring arylnaphthalene lignans (ANLs) are subclass of lignans in many dietary or medicinal plants. The progressing interest of ANLs is due to their diversified biological activities. Herein, we developed a convenient method for the preparation of naturally occurring ANLs and their analogs through the continuous photoflow intramolecular Diels–Alder reaction in several minutes under mild conditions with good yields and regioselectivities.

Synthesis of naphthalene amino esters and arylnaphthalene lactone lignans through tandem reactions of 2-alkynylbenzonitriles

Tandem reaction of 2-alkynylbenzonitriles with a Reformatsky reagent turned out to be a novel and efficient approach toward 1-aminonaphthalene-2- carboxylates. Interestingly, with 2-(3-hydroxyprop-1-ynyl)benzonitriles as the substrates, a more sophisticat

A new benzannulation reaction and its application in the multiple parallel synthesis of arylnaphthalene lignans

A new aromatic annulation reaction based on sequential Horner-Emmons and Claisen condensation reactions is described. The method is high yielding and provides a rapid entry to arylnaphthalenes. The lignan natural products justicidin B 1, retrojusticidin B 2, taiwanin C 3, justicidin E 4, chinensin 5 and retrochinensin 6 have all been synthesised in good overall yield using this protocol, demonstrating its potential in multiple parallel synthesis. The selective oxidation of diols 34-36 to the corresponding retrolactones with barium manganate(VI) is also noteworthy.
