Modi, Anju,Sau, Prasenjit,Patel, Bhisma K.
, p. 6128 - 6131 (2017)
A base-promoted synthesis of quinoline-4(1H)-thiones has been accomplished from the in situ generated o-alkynylthiourea, obtained by reacting o-alkynylanilines with aroyl/acyl isothiocyanates. A 6-exo-dig S-cyclization of the in situ generated thiourea is
