A one-pot sequential strategy to construct phosphonamidates has been developed by generating phosphonites in situ from arylmagnesium bromides and triethyl phosphite followed by treatment with iodine and amines. A variety of phosphonamidates were obta

A Pd(OAc)2-catalyzed tandem cyclization–coupling reaction of (o-ethynylphenyl)phosphonic acid monoesters and allyl halides has been developed. This reaction provides an efficient, mild, general and regioselective way to synthesize 4-allylphosphaiso

Poria cocos (P. cocos) polysaccharides (PCPs) are used to improve immunity and possess antitumor activities. We compared three cultivars of P. cocos (5.78, XJ 28 and JHYH) PCP contents. Then we determined that malZ, galA, SORD, gnl and bglX are key e

A new class of non-benzo halo-enol phostones was synthesized by using a DMAP-catalyzed [DMAP = 4-(dimethylamino)pyridine] halocyclization reaction of 4-pentynylphosphonic monoesters with N-bromosuccinimide (NBS) or N-iodosuccinimide (NIS) in CHCl3 at

A series of phosphorylated flavonoids were synthesized and investigated in vitro as inhibitors of pancreatic cholesterol esterase (CEase) and acetylcholinesterase (AChE). The results showed that most of the synthesized compounds exhibited nanomolar p
