Synthesis and Structural Elucidation of a New Zooecdysteroid Gerardiasterone. -The synthesis of the title compound (IV), isolated from the mediterranean zoanthid Gerardia savaglia, is achieved via asymmetric dihydroxylation of the E-olefin (III) using equimolar amounts of the hydroxylation system.

โฆ Synopsis
Synthesis and Structure Elucidation of New Thiazolotriazepines. -New title compounds, which are of biological interest, can be prepared by reaction of triazepinethiones like (II) with 2-haloketones or condensation of chalcones with iminothiazolines. Their structures are determined by comprehensive one-and two-dimensional NMR spectroscopy. Interestingly, under acidic conditions hydrazones such as (X) undergo ring closure to pyrazoles like (XI). Expected thiazolo[2.3-c]triazepines are not formed.
