Dicyclohexyl carbodiimide cyclodehydration

The same oximino acid (49) underwent a cyclodehydration on treatment with dicyclohexyl carbodiimide to form the unsaturated hydroxamic acid (52) in almost quantitative yield. [Pg.213]

Ph R = H). Other cyclodehydrating agents used to prepare meso-ionic l,3-oxazol-5-ones (66) include oxalyl chloride or dicyclohexyl-carbodiimide. ... [Pg.17]

Topliss reductively cyclized JV-(2-nitro-4-chlorophenyl)-JV-inethyl-2-benzo-ylbenzamide to dibenzo[b,/]-l,4-diazocine 10(67JMC642 68USP3409608). Cyclodehydration of N-(2-aminoethyl)-lV-2-(4-chlorobenzoyl)benzylben-zenesulfonamide afforded tetrahydro-2,5-benzodiazocine II (67JOC3270 70USP3496164). Cyclization of the diamino acids 12 using dicyclohexyl-carbodiimide (DCC) resulted in formation of benzodiazocines 13. Com-... [Pg.187]
