William T. Colwell - Menlo Park CA
James R. Piper - Birmingham AL

International Classification:

C07D47508

US Classification:

544260

Abstract:

A process is provided for the preparation of 10-deazaaminopterins and 5,10- and 8,10-dideazaaminopterins starting from the corresponding homoterephthalic acid diester coupling the corresponding dicarboxylic acid diester having the formula: ##STR1## with the corresponding diaminopterin 6-methylene halide having the formula: ##STR2## thereby forming a pteroic acid diester having the formula: ##STR3## hydrolysing the two ester groups to form the corresponding carboxylic acid groups, and then monodecarboxylating the diacid, thereby removing the carboxylic acid group attached to the carbon alpha to the A group and forming a pteroic acid.

Abstract:

A center body assembly for a lean direct injection fuel injector is disclosed. The center body assembly defines a primary liquid passage, a liquid gallery, a liquid main first passage, a liquid main second passage, and an atomizer assembly. The primary liquid passage supplies liquid fuel to the liquid gallery. The liquid gallery aligns with the primary liquid passage and distributes fuel to the liquid main first passage, and subsequently to the liquid main second passage. The atomizer assembly is in flow communication with the liquid main second passage and provides atomized fuel for combustion.
