N, N’dimethylformamide (DMF) was dried over 4 Å molecule sieves powder. 4Ǻ molecular sieves powder was activated by heating in oven at 120 o C for 24 hours. Triethylamine was stand over KOH solid overnight and distilled before use. Tetrahedron furan (THF) was distilled from Na metal before use. All the other chemicals were bought from commercial source and used directly after arrival.","PeriodicalId":12850,"journal":{"name":"Heterocycles : an international journal for reviews and communications in heterocyclic chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85766590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
