A novel annulation reaction of trans-2-substituted-3-nitrocyclopropane-1,1-carboxylates with in situ generated Huisgen zwitterions is reported, providing facile synthesis of 3-alkoxy pyrazolines in good yields and high diastereoselectivities. This reactio

An efficient and straightforward one-pot synthetic protocol has been developed for the synthesis of 3-arylindolizine- 1-carboxylates via 1,3-dipolar annulation of 2-(2-nitro-1-arylethyl)malonates with pyridine and subsequent aromatisation in the presence of molecular iodine. The structure of methyl 3-(4-methoxyphenyl)indolizine-1-carboxylate (2a) and methyl 3-iodo-2-(4- nitrophenyl)indolizine-1-carboxylate (2f) was further confirmed by X-ray single crystal analysis.

Highly enantioselective Michael addition of malonates to nitroolefins catalyzed by chiral bifunctional tertiary amine-thioureas based on saccharides
Li, Xiao-Juan,Liu, Kun,Ma, Hai,Nie, Jing,Ma, Jun-An
scheme or table, p. 3242 - 3246 (2009/06/25)
A series of saccharide-derived bifunctional tertiary amine-thioureas for the asymmetric Michael addition reaction have been designed and synthesized. The addition products between malonates and various nitroolefins were obtained in high yields (up to 99%)
1,5,7-Triazabicyclo[4.4.0]dec-5-ene (TBD) catalyzed Michael reactions

1,5,7-Triazabicyclo[4.4.0]dec-5-ene (TBD), a bicyclic guanidine base, has been found to be an excellent catalyst for Michael and Michael-type reactions. A wide variety of Michael donors and acceptors can participate in these reactions using 10-20 mol % of
