A convenient synthesis of 2-phenylglycerol
Klis,Erhardt
, p. 4027 - 4038 (2007/10/03)
1,3-Dihydroxyacetone dimer is treated with trimethylsilyl chloride and triethylamine in dichloromethane to provide monomeric ketone having both of its alcohols protected as their di-TMS ethers. The latter is added to phenylmagnesium bromide in ether at -78°C. Work-up by treatment with aqueous ammonium chloride followed by 2 N HCl provides 2-phenylglycerol in 70% yield.
Reactivity and selectivity in the oxidation of styrene derivatives. V. studies on the oxidation of α-substituted styrenes

The liquid phase oxidation of α-phenyl-1a, α-trimethylsilyloxy 1b, α-cyclopropyl-1c, α-trifluoromethyl-1d styrene, and styrene 1e with oxygen in chlorobenzene and cumene solution in the temperature range 55-125°C was investigated. The product yields were determined gaschromatographically. The epoxide selectivity increases up to 90°C with increasing temperature. The epoxides of 1a and 1c rearrange at higher temperatures, therefore their yield decreases. The relative chain propagation constants (kpC=C) were determined by competitive oxidations of cumene.

The asymmetric reduction of aromatic and aliphatic ketones, halogeno ketones, keto esters, and ketone oxime ethers with reagents prepared from borane and chiral amino alcohols has been investigated.When α,α-diphenyl-β-amino alcohols, such as (2S,3R)-(-)-2-amino-3-methyl-1,1-diphenylpentanol (2d), were used as a chiral auxiliary, very high enantioselectivities (ca. 90percent e.e.) were obtained in the reduction of various ketones and oxime ethers.
