Masjedizadeh and coworkers have recently described similar microwave-promoted hydrogen-deuterium exchange reactions in a series of heterocydes using mixtures of deuterium oxide and deuteriomethanol (Scheme 6.173 b) [328], The rapid exchange method was applied to the deuteration of the anti-tumor antibiotic bleomycin A under catalyst-free conditions [328],... 

The intramolecular G-H insertion of aryldiazoacetates is a very powerful strategy for synthesizing heterocyclic rings such as dihydrobenzofurans and dihydrobenzopyrans. The first effective asymmetric copper-catalyzed C-H activation reaction was reported by the group of Sulikowski in the synthesis of the anti-tumor antibiotic FR-66979 93 (Scheme 7)123 219 The G-H insertion of the aryldiazoacetate 90 formed four diastereomeric products 91a, 91b, 92a,... 

The densely functionalized cyclopentyl core 10 of the potent anti-tumor antibiotic viridenomycin 11 was prepared by treatment of enone 8 with catalyst C (Scheme 2). This reaction proved to be very slow, requiring 3.5 days to give still only incomplete conversion leading to cyclization product 9 in 69% (86%, based on recovered 8). 

Kedarcidin is a chromoprotein anti-tumor antibiotic, produced by an actinomycete strain. It is an acidic complex with an apparent molecular weight of 12,400 Da, and it consists of an apoprotein and a cytotoxic highly unstable nonprotein chromophore 12 that possesses a conformationally defined ansamacrocyclic bridge. Retrosynthetically,...

The Pictet-Spengler reaction has also been developed on solid-support materials. This advancement provided the opportunity for the synthesis of an array of structurally diverse analogues of saframycin A, an important anti-tumor antibiotic.
