An N-heterocyclic carbene (NHC) catalyzed γ-specific aldol-like reaction between allenoates and isatins has been achieved under mild conditions, giving trisubstituted allene derivatives bearing isatin moiety in moderate to good yields with high diastereoselectivity and excellent atom efficiency. The DFT computations indicated that the formation of the γ-adduct was more energetically favorable than that of the α-adduct. The result reported herein opens a new route for NHC-promoted allenoate-involved reaction.

In the search for antitumor active metal complexes several ruthenium complexes have been reported to be promising. A series of mononuclear Ru(II) complexes, [Ru(T)2(S)]2+, where T = 2,2'-bipyridine/1,10- phenanthroline and S = CH3-bitsz, Cl-bitsz, Br-bitsz, tmtsz, dmtsz, have been prepared and characterized by UV-Vis, IR, 1H-NMR, FAB-mass spectroscopy, and elemental analysis. The complexes were subjected to invivo anticancer activity against a transplantable murine tumor cell line Ehrlich's ascitic carcinoma (EAC) and invitro cytotoxic activity against human cancer cell line Molt 4/C8, CEM, and murine tumor cell line L1210. Ruthenium complexes showed promising biological activity especially in decreasing tumor volume and viable ascitic cell counts. Treatment with these complexes prolonged the life span of EAC-tumor-bearing mice by 10-48%. Invitro evaluation of these ruthenium complexes revealed cytotoxic activity from 0.21 to 24 mol L -1 against Molt 4/C8, 0.16-19 μmol L-1 against CEM, and 0.75-32 μmol L-1 against L1210 cell proliferation, depending on the nature of the compound.
