N-Cbz-2-trimethylsilyl-1,3-thiazolidine can be easily functionalized under fluoride ion conditions with aldehydes as electrophiles. The reaction selectively affords new cyclo-fused oxazolidinones or homologated α-hydroxy thiazolidines depending on the temperature of the reaction and the nature of the aldehyde.
在氟离子条件下,N-苄氧羰基-2-三甲基硅基-1,3-噻唑烷很容易与作为亲电体的醛发生官能化反应。根据反应温度和醛的性质,该反应可选择性地生成新的环融恶唑烷酮或同源的δ-羟基噻唑烷。
