Novel and efficient synthesis of uracil phosphonate derivatives via pentacovalent oxaphospholenes
摘要:
2,2,2-Triethoxy-1,2lambda5-oxaphospholene, 1, reacts under mild, neutral conditions with aryl isocyanates to produce the phosphonate-containing pyrimidinedione derivatives 2 and 3. X-ray structure determination of 3 confirmed its structure.
