Hindered organoboron groups in organic chemistry. 21. The reactions of dimesitylboron stabilised carbanions with oxiranes

Dimesitylboron stabilised carbanions react with oxiranes to give products that can be oxidised to 1,3-diols. The reactions are, in general, under steric rather than electronic control, and proceed smoothly for all but tetrasubstituted oxiranes. Some unusual stereoselective effects have been observed.

Here we report a novel and efficient method for the regioselective mono-deprotection of di-terf-butylsilylene acetals derived from 1,3-diols consisting of primary and secondary alcohols. The ammonium fluoride-mediated reactions of pyripyropene A derivative, thymidine and uridine derivatives, methyl β-D-glucofuranoside, and pyranoside derivatives each gave the corresponding primary alcohol with high regioselectivity.
Direct catalytic asymmetric enolexo aldolizations

32 years after the first, and still the only, catalytic asymmetric intramolecular aldol reaction was published in this journal, the proline-catalyzed Hajos-Parrish-Eder-Sauer-Wiechert reaction is extended for the first time to catalytic asymmetric enolexo
Rhodium-catalyzed reformatsky-type reaction
Kanai, Kazuo,Wakabayashi, Hitoshi,Honda, Toshio
, p. 2549 - 2551 (2007/10/03)
(equation presented) A novel Reformatsky-type reaction was developed using RhCl(PPh3)3 and diethylzinc. Inter- and intramolecular Reformatsky-type reactions were achieved efficiently under mild reaction conditions to give β-hydroxy esters.
