We report a strategy for the conversion of aldehydes to enantiomerically enriched alpha-amino boronates through the intermediacy of in situ-generated silylimines. This transformation is brought about by Pt-catalyzed asymmetric addition of B2(pin)2 across the imine double bond. An attractive feature of the intermediate diboration adduct is that it can be acylated directly and provides convenient access to important N-acyl alpha-amino boronic ester derivatives.

(Chemical Equation Presented) The synthesis of monodisperse oligo(p-phenyleneethynylene)s 8an with alternating 2,5-dihexyl-1,4-phenylene and 6,14-di-tert-butyl-1,4-triptycylene units and orthogonally protected alkyne end groups is reported. Starting from 6,14-di-tert-butyl-1-(2-triisopropylsilylethynyl)-4-(2-trimethylsilylethynyl) -triptycene (5a), 1,4-dihexyl-2,5-diiodobenzene (10), and 1,4-dihexyl-2-iodo-5- (3-hydroxyprop-1-ynyl)-benzene (9), oligomers with up to four repeating units, i.e., eight phenyleneethynylene units, were prepared through a partially divergent-convergent route with the alkynyl-aryl (Sonogashira-Hagihara) coupling as the key reaction. The starting compound 5a was prepared from triptycenequinone through a sequence of addition of 2- trialkylsilylethynyllithium, reduction and concomitant elimination of water, conversion of the phenol into a triflate, and finally Pd/Cu-catalyzed coupling with trialkylsilylethyne. A similar access to the key compound for a stringent divergent-convergent route, 6,14-di-tert-butyl-1-(3-hydroxybut-1-ynyl)-4-(2- triisopropylsilylethynyl)triptycene (6), is reported. The optical properties of the oligomers 8an and the corresponding oligo(2,5-dihexyl-1,4- phenyleneethynylene) s in dilute solution are almost identical, whereas they differ significantly for the solid, undiluted compounds.

The stereoselective addition of the 2-hydroxyl group of glucose to the mercurated vinyl group of 2-alkenyl glycosides followed by hydride reduction and removal of the saccharide fragment was used to prepare enantiomerically pure 1,2-dihydroxy alkanes. Diols of (R) or (S) configuration can be synthesized from (alpha)-glycosides or the (beta) form respectively. Demercuration with chloride ion led to the insertion of a halo group adjacent to the new chiral center thus allowing for the possibility of further functionalization.
