Abstract: A series of 2-substituted and 2,3-disubstituted 5-cyanoindolizine derivatives were conveniently synthesized by a one-pot tandem reaction under mild conditions in moderate yields. The reaction mechanism was proposed.
Structure–Activity Relationship of Pyrrolyl Diketo Acid Derivatives as Dual Inhibitors of HIV-1 Integrase and Reverse Transcriptase Ribonuclease H Domain
The development of HIV-1 dual inhibitors is a highly innovative approach aimed at reducing drug toxic side effects as well as therapeutic costs. HIV-1 integrase (IN) and reverse transcriptase-associated ribonuclease H (RNase H) are both selective targets for HIV-1 chemotherapy, and the identification of dual IN/RNase H inhibitors is an attractive strategy for new drug development. We newly synthesized pyrrolyl derivatives that exhibited good potency against IN and a moderate inhibition of the RNase H function of RT, confirming the possibility of developing dual HIV-1 IN/RNase H inhibitors and obtaining new information for the further development of more effective dual HIV-1 inhibitors.

A novel and efficient method was developed for the synthesis of nitrogen bridgehead heterocycles with phosphonates. Nitrogen containing five-membered heterocyclic aldehyde and diethyl 3-bromoprop-1-enylphosphonate were used as substrates. Bridgehead nitrogen-containing arylphosphonates were obtained via one-pot reaction including four steps: S(N)2, deprotonation followed by electron flow, nucleophic additon and elimination of water.
