(−)‐Alternarlactam [(−)‐1], a new promising cytotoxin against two human cancer cell lines, was isolated from an endophyte culture and synthesized (along with (+)‐1) from readily available starting materials. The absolute configuration, chirality–activity relevance and self‐aggregation of (−)‐1 were assigned by a combination of synthetic, spectroscopic and computational approaches.

The present invention relates to the field of organic synthesis. More specifically, it concerns a process for the selective reduction of a C3-C70substrate containing one or more carbonyl or carboxylic functional groups into the corresponding 5 alcohol diol, or polyalcohol in the presence of a silane and at least one catalyst or pre-catalyst in the form of a zinc complex. The Zinc complex of formula (I) or (II) is also part of the invention.
