The synthesis of a new photolabile protecting group for carboxylic acids, alpha-carboxy-6-nitroveratryl (alphaCNV), is described. Bromide 3, prepared in four steps from 3,4-dimethoxyphenylacetic acid, was used to alkylate carboxylic acids under mild

The synthesis is reported of 2-hydroxy-1,2,2-triphenylethanone esters of carboxylic acids by the reaction between 2-chloro-1,2,2-triphenylethanone and a carboxylic acid in the presence of silver carbonate and silver tetrafluoroborate. Photolysis of t

The first spirobifluorenes comprising two binaphthyl moieties with silicon or germanium at the site of fusion have been synthesized and fully characterized. X-ray crystallographic analysis reveals that both molecules have highly distorted structures,

The synthesis of photolabile tyrosine derivatives protected on the phenolic oxygen by the α-carboxy-6-nitroveratryl (αCNV) protecting group is described. The compounds undergo rapid photolysis at wavelengths longer than 300 nm to liberate the corre

A novel approach to 2,4-disubstituted piperidines is reported, involving the radical cyclization of 7-substituted-6-aza-8-bromooct-2-enoates. Cyclization with tributyltin hydride affords the trans piperidines with trans/cis diastereomeric ratios rang

Cyclisation of bromides 4a-f mediated by tributyltin hydride affords predominantly the trans piperidines 5a-f with modest diastereomeric ratios, while cyclisation with tris(trimethylsilyl)silane affords the same products with diastereomeric ratios of
