Rhodium-catalyzed reformatsky-type reaction

(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.

Regioselective mono-deprotection of di-ferf-butylsilylene acetal derived from 1,3-diol with ammonium fluoride

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.

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.
