A series of fused bicyclic thiazole and thiophene derivatives which are substituted in the 2-position by an optionally substituted morpholin-4-yl moiety, and in the 4-position by hydroxy, oxo or an amine moiety, being selective inhibitors of PI3 kinase enzymes, are accordingly of benefit in medicine, for example in the treatment of inflammatory, autoimmune, cardiovascular, neurodegenerative, metabolic, oncological, nociceptive or ophthalmic conditions.

pyridyltrimethylsilanes allowed us to perform efficient Hiyama cross-coupling with various (het)arylhalides. The reactions proceeded smoothly at room temperature leading to the corresponding functional bis(het)aryl in fair to excellent yields. The presence of pyridine nitrogen alpha to the trimethylsilyl group was requisite to achieve the cross-coupling. [Reaction: see text]

Described herein is a new asymmetric synthesis of imines to obtain β-carboline derivatives useful as key intermediate compounds for the synthesis of phosphodiesterase inhibitors using a new process with palladium or ruthenium hydride and/or nickel boride to reduce chiral intermediates. The use of chloroformate chiral auxiliaries is further described for the reduction and asymmetric hydrogenation of imines to obtain β-carboline derivatives and intermediate compounds used in the preparation thereof.
A series of 5,6-dihydro-1-benzothiophen-7(4H)-one derivatives, and analogues thereof, which are substituted in the 2-position by an optionally substituted morpholin-4-yl moiety, being selective inhibitors of PI3 kinase enzymes, are accordingly of benefit in medicine, for example in the treatment of inflammatory, autoimmune, cardiovascular, neurodegenerative, metabolic, oncological, nociceptive or ophthalmic conditions.
