A first aspect of the invention relates to a compound of formula (I), or a pharmaceutically acceptable salt or ester thereof, wherein: • B is an aryl or heteroaryl group optionally substituted by one or more R10 groups; and * X is selected from 0, (CR11 R12 ) p and (CR11 R12 ) p CO. Said compounds are capable of inhibiting PAICS and are useful in the treatment of proliferative disorders. Further aspects relate to pharmaceutical compositions, therapeutic uses and process for preparing compounds of formula (I).

Di-<i>tert</i>-butyl Peroxide-Mediated Radical C(sp<sup>2</sup>/sp<sup>3</sup>)–S Bond Cleavage and Group-Transfer Cyclization
cascade radicalC(sp2/sp3)-S bond cleavage and group-transfer cyclization is disclosed. Triggered by alkyl radicals, varieties of 2-isocyanoaryl thioethers containing aliphatic, aryl, and heteroaromatic groups can be cleaved and precisely reinstalled to give benzothiazole derivatives. Mechanistic studies reveal that the cascade reaction undertakes an intermolecular pathway, and the inner radical sources

BrCF2COOEt plays a dual role as a C1 synthon and a difluoroalkylating reagent for the first time. Mechanistic studies supported by DFT calculations suggest that a base plays an active role in the formation of the key intermediate isocyanides generated in situ from primary amines and difluorocarbene.

The invention relates to a process for preparing N-(1-phenylethyl)anilines, salts, and solvates thereof, to novel intermediates, and to the use of the intermediates in the preparation of serotonin 5-HT6 antagonists.
A metal-free radical cascade cyclization of 2-isocyanoaryl thioethers with alcohols has been developed. It provides a novel and effective method to synthesize diverse 2-hydroxyalkyl benzothiazoles with broad substrate scope, good functional group tolerance and moderate to excellent yields.
