Climatic perturbation during the Pleistocene era has played a major role in plant evolutionary history by altering species distribution range. However, the relative roles of climatic and geographic factors in the distribution dynamics remain poorly u

Four steroidal ketones were isolated from the holdfast of cultivated Laminaria japonica. The structures were characterized as ergosta-4,24(28)-diene-3-one (1), ergosta-4,24(28)-diene-3,6-dione (2), stigmasta-4,24(28)-diene-3-one (3) and stigmasta-4,2

The formal total synthesis of the marine metabolite (+)-calyculin A is reported. The key steps involve (i) the use of Brown allylboration chemistry to control the relative and absolute stereochemistry of homoallylic alcohol arrays, thus setting eight

A direct spectrophotometric method for the simultaneous determination of nitrate and nitrite by column preconcentration has been developed. Nitrate is reduced to nitrite in a copper-coated cadmium column which is then treated with azo dye reagent by

The C16-C36 unit of halichondrin B was stereoselectively synthesized via the aldol condensation of two C16-C26 esters with the previously synthesized C27-C36 aldehyde followed by E ring construction. The C16-C26 esters were prepared starting from (2S
