Chiral α-Hydroxy Acids: Racemic 2-Hydroxy-2,3,3-trimethylbutanoic Acid and 2-Hydroxy-2-trimethylsilylpropanoic Acid
摘要:
Both C7H14O3 and C6H14O3Si crystallize as racemates from acetone solution, the former incorporating water of crystallization (C7H14O3.0.5H(2)O). The crystal structures display extensive intermolecular hydrogen bonding involving the hydroxy and carboxylic acid groups to give polymeric networks.

The reaction of dimethyldioxirane with several alkynes gives products which are conveniently rationalized by postulating the intermediacy of oxirenes and oxocarbenes. The latter serve as precursors to H atom or methyl group migration products, as well as to cyclopropane insertion products in some cases. Alkenes, derived from some of these carbene reactions, are partially converted to epoxides.
