One-pot synthesis of 4-substituted 4-alkoxy-1,4-dihydro-3,1-benzoxazine-2-
thiones by the reaction of 2-isothiocyanatobenzoates with organolithiums。

An efficient one-pot procedure for the preparation of 4-substituted 4-alkoxy-1,4-dihydro-3,1-benzoxazine-2-thiones from 2-isothiocyanatobenzoates has been developed. Thus, 2-isothiocyanatobenzoates were reacted with organolithiums including lithium enolates of acetates and tertiary acetamides in THF at 78 C to give the desired products in generally good yields.

通过2-isothiocyanatobenzoates 和有机锂一步合成4-取代-4-烷氧基-1,4-二氢-3,1-苯并恶嗪-2-硫酮
提出了一种有效的一步法来合成4-取代-4-烷氧基-1,4-二氢-3,1-苯并恶嗪-2-硫酮。用2-isothiocyanatobenzoates  和有机锂(包括醋酸烯醇化锂和三级乙酰胺)在78℃THF溶液中能得到较高产率的产品。
