Abstract: Methods for preparing a variety of bryostatin compounds are provided. The subject methods provide for preparation of bryostatin 1 in multi-gram quantities in a low and unprecedented number of convergent synthetic steps from commercially available materials. The subject methods are scalable with low estimated material costs and can provide enough material to meet clinical needs. Also provided are a variety of bryostatin analog compounds, and prodrug forms thereof, which are synthetically accessible via the subject methods and pharmaceutical compositions including the same.

Abstract: The present invention relates to an integrated synthesis gas refinery plant and a process for the simultaneous production from a single synthesis gas stream X of a hydrogen stream useful for the production of ammonia, a hydrogen rich synthesis gas stream useful for the production of methanol, and a hydrogen depleted synthesis gas stream useful for the production of hydrocarbons.

Abstract: An endothermic reaction furnace includes one or more elongated reaction tubes defining therein an endothermic reaction flow path and a combustion flow path for providing heat to drive the endothermic reaction. The combustion flow path is arranged so that fuel and combustion air are separately heated by the heat inside the furnace preferably to significantly above their autoignition temperature before being combined in a combustion zone where they mix, autoignite and burn. The fuel is introduced into the combustion zone by a plurality of tubes having outlet ends arranged to produce annular shrouds of flame around each reaction tube that are directed countercurrent to the endothermic reaction product.

Abstract: This invention relates to a process for cracking waste polymers in a fluidized bed reactor to produce vaporous products comprising primary products which can be further processed, eg in a steam cracker to produce olefins, characterized in that the vaporous products are treated to generate a primary product substantially free of a high molecular weight tail having molecular weights >700 prior to further processing. The removal of the high molecular weight tail minimizes fouling and prolongs the lifetime of the reactors used for further processing.
