Abstract: The present invention relates to processes useful in the preparation of morphine analogs and derivatives, such as naltrexone, naloxone and nalbuphine and intermediates in the synthesis of said morphine analogs and derivatives. In a particular example, the process begins with for example oxymorphone, oxycodone, 14-hydroxycodeinone or 14-hydroxymorphinone, and includes the formation of an oxazolidine-containing intermediate using catalytic oxidation.

Abstract: The present invention provides a board game adaptable to one, two or three levels of play wherein the game board may be set correspondingly to one, two or three physical levels. The board is preferably round and accommodates two, three or four players. Game pieces are placed on the board, during play, from a choice of spots on an outer ring of the game board and progress inwardly toward the center of the board. When a player is able to position his four different color game pieces at the center of the board on corresponding colored game piece spots, and then move the pieces to a home board, he or she is the winner.

Abstract: Binuclear iridium (I) phosphine complexes of the general formula: ##STR1## in which X is fluorine, chlorine, bromine or iodine, and ##STR2## is in each case a chiral bidentate diphosphine ligand. The complexes are particularly suitable as catalysts for the inter- or intramolecular asymmetric hydroamination of prochiral olefins.
