aryl halide-containing β-aryl ketones and aldehydes can be synthesized directly from readily available allyic alcohols and boronic acids via palladium-catalyzedoxidativecross-coupling reactions. The dual roles of copper, including electron-carrier and Lewis acid functions, are supposed to be critical for the high reactivity and selectivity of this aerobic oxidative coupling transformation.

taste of four fluoro substituted derivatives (2a, 2b, 2c and 2d) is almost indistinguishable from that of the parent compound 4-(4-hydroxyphenyl)butan-2-one (1), the main flavor component of raspberries. The same holds for the comparison between the corresponding acetate, another raspberry ingredient, and its 1-fluoro analogue (2e). In contrast, methyl substituents (as present in compounds 3a, 3b, 3c

In one aspect, this invention relates to production of useful fermentation end-products from biomass through simultaneous hydrolysis and fermentation by a microorganism, such as
Clostridium phytofermentans
. The invention also relates to the development of a process for efficient pretreatment and conversion of lignocellulosic biomass to end-products with high conversion efficiency (yield). In another aspect, methods for producing a fermentation end-product by fermenting hexose (C6) and pentose (C5) sugars with a microorganism, such as
Clostridium phytofermentans
are disclosed herein.

Disclosed herein are analogues of itraconazole that are potent hedgehog signaling pathway inhibitors. The compounds are expected to be useful in the treatment of cell proliferation disorders such as cancer, particularly cancers that are dependent upon the hedgehog signaling pathway such as basal cell carcinoma and medulloblastoma.

Allylic alcohols, 1-buten-3-ol, 1-penten-3-ol and 1-octen-3-ol, reacted with aryl iodides (iodotoluene, 4-iodotoluene, 4-iodophenol and 4-iodanisole) under Heck reaction conditions to form corresponding saturated aryl ketones in one step. The same products were obtained in a two-step tandem reaction consisted of the Heck coupling of allylic alcohols with aryl iodides, followed by hydrogenation. Reactions
