Abstract
A straightforward enantiomerically pure synthesis of the heterocyclic core of the D-series GE2270 is reported. The synthetic strategy combines the Hantzsch thiazole's building condensation with a cross-coupling reaction including direct C-H hetarylation to build and connect step-by-step thiazolyl moieties to the 5-bromopicolinate as readily available starting material.

Abstract
Two new thiazole and thiadiazole alkaloids, penicilliumthiamine A and B (2 and 3), were isolated from the culture broth of Penicillium oxalicum, a fungus found in Acrida cinerea. Their structures were elucidated mainly by spectroscopic analysis, total synthesis and X-ray crystallographic analysis. Biological evaluations indicated that compound 1, 3a and 3 exhibit potent cytotoxicity against different cancer cell lines through inhibiting the phosphorylation of AKT/PKB (Ser 473), one of important cancer drugs target.

Abstract
The first examples of thiazolo[4,5-e]benzoisoxazoles are obtained from bromination of dihydrobenzo[d]isoxazol-4(5H)-one followed by cyclocondensation with thiourea, in the presence of DDQ. Analogously, cyclocondensation with thioamides provided 7,8-dihydrothiazolo[4,5-e]benzoisoxazoles. A 55-member library of these heterocycles is reported.
