FUNCTIONALIZED PRIMARY ALKYLTRIFLUOROBORATE SALTS AND METHOD FOR MAKING THE SAME

The invention provides methods for preparing boronic acids, for example, primary alkyl or alkenyl boronic acids, and alkali metal alkyl trifluoro borate salts, as described herein, wherein the primary alkyl boronic acids and the potassium alkyl trifluoroborate salts can contain one or more unprotected functional groups.

Transfer of alk-1-enyl group from boron to tin: A highly stereoselective synthesis of (E)-alk-1-enyltributylstannanes

Treatment of (E)-alk-1-enyldicyclohexylboranes with tributyltin methoxide in the presence of galvinoxyl (1 mol%) at room temperature results in transfer of the alk-1-enyl group from boron to tin to give (E)-alk-1- enyltributylstannanes in a highly stereoselective fashion. Subsequent halodestannylation of (E)-alk-1-enyltributylstannanes is allowed to proceed in a one-pot manner to produce the corresponding (E)-1-iodoalk-1-enes and (E)-1-bromoalk-1-enes in good to high yields, respectively.

Enantioselective addition of vinylzinc reagents to aldehydes catalyzed by modular ligands derived from amino acids

A series of N-acylethylenediamine-based ligands were synthesized from Boc-protected amino acids. The ligands were screened for the ability to catalyze the asymmetric addition of vinylzinc reagents to aldehydes. Three sites of diversity on the ligands were optimized for this reaction using a positional scanning approach. The optimized ligand 3d was found to catalyze the formation of 15 different (E)-allylic alcohols with enantioselectivities that ranged from 52 to 91% ee and yields that ranged from 40 to 90%. This ligand was especially effective for the reaction of aromatic aldehydes with vinylzinc reagents derived from bulky terminal alkynes. Ligand 3d catalyzed the addition of (E)-(3,3-dimethylbut-1-enyl)(ethyl)zinc to 2-naphthaldehyde to give (R,E)-4,4-dimethyl-1-(naphthalene-1-yl)pent-2-en-1-ol in 89% ee. The ee of this product could be increased to 97% through a single recrystallization.
