C60 and C70 adducts containing spacer-linked phenyl (BK1), 9-anthracenyl (BK2), 4-(9-anthracenyl)phenyl (BK3), and 1-pyrenyl groups (BE1 and FE1) have been studied. Two different synthetic pathways were employed based on the [4+2] cycloaddition of fullerenes with 2-trimethylsiloxy-1,3-butadienes (TB). Spectroscopic data for the new compounds are given.

Biocatalytic deracemisation of racemic allylic alcohols by whole cells of Candida parapsilosis ATCC 7330 resulted in the formation of the (R)-enantiomers in high enantiomeric excesses (up to >99%) and isolated yields (up to 79%). (C) 2008 Elsevier Ltd. All rights reserved.

Synthesis and antiproliferative action of a novel series of maprotiline analogues
The synthesis of a diverse library of compounds structurally related to maprotiline, a norepinephrine reuptake transporter (NET) selective antidepressant which has recently been identified as a novel in vitro antiproliferative agent against Burkitt's lymphoma (BL) cell lines is reported. A series of 9,10-dihydro-9,10-ethanoanthracenes were synthesised with modifications to the bridge of the dihydroethanoanthracene structure and with alterations to the basic side chain. A number of compounds were found to reduce cell viability to a greater extent than maprotiline in BL cell lines. In addition a related series of novel 9-substituted anthracene compounds were investigated as intermediates in the synthesis of 9,10-dihydro-9,10-ethanoanthracenes. These compounds proved the most active from the screen and were found to exert a potent caspase-dependant apoptotic effect in the BL cell lines, while having minimal effect on the viability of peripheral blood mononuclear cells (PBMCs). Compounds also displayed activity in multi-drug resistant (MDR) cells. (C) 2013 Elsevier Masson SAS. All rights reserved.
