✦ Synopsis

Low-valent cobalt complexes were used in Reformat&y-type additions of a-halophosphonates to carbonyl compounds (ketones and aldehydes) to yield a variety of P-hydroxyphosphonates.

An enantiodivergent strategy for the synthesis of trans-3,4-disubstituted succinimides is reported. The key step is a highly transstereoselective SmI 2 -induced Reformatsky-type reaction of 4-substituted-O-benzoylated malimides with carbonyl compounds. Double chirality transmissions were performed w
