Synthesis and Reactions of Some New Spiropyranthiazoline Derivatives
摘要:
Pyrano[2,3-d]thiazoline-7-spiro-3'-(1'-substitutedindoline-2'-ones) 5a,b has been synthesized and reacted with some nucleophile reagents to afford new spirothiazolino[4,5:2',3']pyrano[6',5'-d]pyrimidine derivatives 6a,b-13a,b, which are analogues of some reported biologically active spiroheterocyclic compounds.
