A series of B-(iododialkyl)boranes and B-(alkyldiiodo)boranes have been readily synthesized as their MeCN complexes from the corresponding chloro- and bromoboranes by treatment with NaI or KI in MeCN. In the presence of EtN(i-Pr)2, the B-(cyclo
THE REACTION OF α,β-EPOXY SULFOXIDES WITH LITHIUM DIMETHYLCUPRATE GIVING ENOLATES: A NOVEL SYNTHESIS OF ALDOLS

The aldols 5 are synthesized from three components (1-chloroalkyl phenyl sulfoxide 1 and two kinds of carbonyl compounds 2 and 4) through α,β-epoxy sulfoxides 3 using lithium dimethylcuprate as an electron-transfer reagent.
Diastereoselective Aldol Addition Using Boron Trichloride or Alkoxydichloroborane
Chow, Hak-Fun,Seebach, Dieter
, p. 604 - 614 (2007/10/02)
Under carefully controlled conditions, boron trichloride or alkoxytrichloroborane/ethyldiisopropylamine in CH2Cl2 can be used to effect diastereoselective aldol additions of ethyl ketones to saturated, α,β-unsaturated, or aromatic aldehydes.The C-C bond formation takes place with relative topicity ul ('syn' configuration of the aldols), in selectivities ranging from 90 to 99percent ds (Tables 1-3).Mechanistic aspects of the reaction are discussed.
ERYTHRO-SELECTIVE ALDOL REACTION USING PHENYLDICHLOROBORANE
Hamana, Hiroshi,Sasakura, Kazuyuki,Sugasawa, Tsutomu
, p. 1729 - 1732 (2007/10/02)
High erythro-selectivity could be attained in the aldol reaction of ethyl ketones with aldehydes using phenyldichloroborane in the presence of ethyldiisopropylamine.
