On December 8, 1982, there was a patent about fungicides.Category: indole-building-block The title of the patent was 1-(α-Chloroacetyl)-6-substituted indolines. And the patent contained the following:
Title indolines I [R = COCH2Cl (II), COCH2NO2] were prepared by acylating I (R = H) in the presence of bases. Thus, 14.7 g ClCH2COCl was added to a mixture of 20 g I (R = H) and 14.4 g Et3N in C6H6 with cooling and the whole stirred 30 min with cooling and 2 h at 30-40° to give 74.8% II. II showed fungicidal activity at 1000 ppm. The experimental process involved the reaction of 6-Chloro-2,3-dihydro-1H-indole(cas: 52537-00-5).Category: indole-building-block
