A new structural phenanthroindolizidine, 2,3,6,7-tetramethoxyphenanthro[9,10,3('),4(')]indolizidine, has been synthesized efficiently from pyrrole. An important feature of this synthesis is that intramolecular oxidative coupling and rearrangement of 6,7-bis(3,4-dimethoxyphenyl)-8-methoxy-1,2,3-trihydroindolizin-5-one by using VOF3 and TFA have been achieved in one pot.

Organocatalytic asymmetric Michael reaction with acylsilane donors
We have developed an organocatalyticasymmetricMichaelreaction of acylsilane through the selection of acylsilane substrates and organocatalysts, thus creating a rare example of acylsilane α-alkylation with a chiral guanidine catalyst, which afforded products in good yields and high stereoselectivity. The corresponding adducts described here have also been demonstrated to be useful in the synthesis
