This quantity had its start from a symposium equipped via the Macromolecular Secretariat of the yankee Chemical Society in Atlanta, GA, 1991. considering the fact that Macromolecular SeCretariat has 5 engaging divisions-Polymer Chemistry; Polymer fabrics: technology and Engineering department; Colloid and floor Chemistry department; Cellulose, Paper and fabric department; and Rubber Division-the audio system have been invited from those disciplinaries and they're really interdisciplinary in multidisciplinary parts.

Schrader indicated that acylacetamides such as I could be dehydrated to I I, but no details were reported. ' 0 k Fused 5/6 Ring Systems with Two Extra Heteroatoms 787 By heating 2-aminobenzothiazoles with paminocrotonic ester, Qntaki and Petrov2 prepared a group of compounds of structure H I (R = H, m.

Dehydrochlorination of VI with alcoholic potash yielded the so-called y-Korper, which was assigned structure VII. However, structure VIII would seem to be an alternative possibility. The only authentic 7-mOnO- - cH3yx3..

Prokof'ev and his co-workers foundg-I ' that guanidine acids such as XI1 may be converted directly into XIV, or may first be cyclized to the 2-amino-4-imidazolinone (XI 11) and this condensed Chapter VI 804 HZN 'y"),' '- C6H6 C,H, J RCOCH,COOC,H, OH with a Fketoester to yield XIV.

The condensation of 2-chlorothiazoles with anthranilic acid, a ynthesis designed to give only the linear product (VIII), was next tudied. ). Since the products prepared from the 2-chlorothiazoles were presumed to be linear (VIII), it was suggested"-12 that the earlier products were the angular (IX) isomers. The condensation of 2-chlorobcnzoic acid with 2-aminothiazoline was reported unsuccessful. T h e condensation of anthranilic acid with ally1 mustard oil yields a product thought to be 3-allyl-2-mercaptoquinazolone or 2,3dihydro-2-methyithiazolo[2,3-b]quinazolin-5-one.
