Abstract
Silylation of alcohols has generally been known to take place at the sterically most accessible less-hindered hydroxy group. However, we report here the catalyst-controlled substrate-selective silylation of primary alcohols, where the selectivity was controlled independent of the innate reactivity of the hydroxy group based on the steric environment. The chain-length-selective silylation of 1, n- amino alcohol derivatives was achieved, where 1,5-amino alcohol derivatives showed outstanding high reactivity in the presence of analogues with a shorter or longer chain length under catalyst-controlled conditions. A highly substrate-selective catalytic silylation of pentanol analogues was also developed, in which the remote functionality at C(5) from the reacting hydroxy groups was effectively discriminated on silylation.

Abstract
The O,O-silyl group migrations on a quinic acid-derived cyclitol have been studied, and the ease of migration was observed to be dependent on the silicon substituents and reaction conditions. Conditions were found to improve the formation of a main isomer during the O,O-silyl group migrations that could be integrated into the formal synthesis of vitamin D receptor modulator VS-105 and in the first total synthesis of a metabolite from the African ant Crematogaster nigriceps.

Abstract
Relative rates for the reaction of secondary alcohols carrying large aromatic moieties with silyl chlorides carrying equally large substituents have been determined in organic solvents. Introducing thoroughly matching pairs of big dispersion energy donor (DED) groups enhanced rate constants up to four times, notably depending on the hydrogen bond donor ability of the solvent. A linear correlation between computed dispersion energy contributions to the stability of the silyl ether products and experimental relative rate constants was found. These results indicate a cooperation between solvophobic effects and DED-groups in the kinetic control of silylation reactions.

Abstract
Herein, we present the use of the tert-butyldimethylsilyl amine (TBDMS-NH2) as a silylating reagent for phenols, benzyl alcohols, and carboxylic acids. Unlike other silyl protection reactions, this reported process with TBDMS-NH2 does not involve the formation of HCl. Importantly, we report the efficacy of this reagent in operating under solvent-free conditions and enabling short reaction times.
