title: A highly efficient synthesis of potent and selective butyrolactam inhibitors of 11beta-HSD1.
abstract: A convergent synthesis of structurally novel butyrolactam 11beta-HSD1 inhibitors is described. The approach features an efficient Ireland-Claisen reaction to construct a highly substituted aldehyde building block which is converted to a lactam via a tandem reductive amination/cyclization sequence. The generality of the synthetic sequence is demonstrated during the preparation of two additional potent 11beta-HSD1 inhibitors.
